1. A group of students went to the movie theater.
Eighteen of the students bought popcorn.
The other 60% of the students bought candy.
How many students were in the group?
2.There are 21,000 fans at a football game cheering for the home team. The other 40% of the total people in attendance are cheering for the away team. How many people are in attendance at the game?
3.Ashley sees a book bag on sale in a store for $22. This is 20% off the original price. What was the original price of the book bag?
Answers
So the other 40% of students is 10 students. In total there are 28 students
2. 21,000 - 40% = 12,600
There are 33,600 people in attendance.
3. $26.40 is the original price
NUMBER 1
If 18 people is 40% that means the we need to start taking 40% off of numbers
40% of 20 is 12
40% of 25 is 15
40% of 30 is 18
So the answer is 30
NUMBER 2
If 21,000 people is 60% that means 20% is 7,000 people and 7,000x5=35,000 so there is a total of 35,000 people at the game
NUMBER 3
You should start taking 20% off of numbers.
20% of 25 is 20 too low so we need to go higher
20% of 26 is 20.8 still too low so lets keep going
20% of 27 is 21.60 closer but too low
20% of 28 is 22.40 which is too high lets go back since 27 is too low and 28 is too high lets start in between
20% of 27.5 is 22.00
So the answer is $27.5.

Diego’s history teacher writes a test for the class with 26 questions. The test is worth 123 points and has two types of questions: multiple choice worth 3 points each, and essays worth 8 points each.
How many essay questions are on the test? Explain your reasoning.
Answers
Answer: 9 essay questions
Step-by-step explanation:
The test has 26 questions
The test is worth 123 points
The test has two types of questions:
Multiple choice worth 3 points each
Essays worth 8 points each
Let the number of multiple choice questions be, m, and the number of essay questions be , e.
This forms a simultaneous equation below:
m + e = 26 ... (i)
3m + 8e = 123 ... (ii)
Multiplying (i) by 3 and (ii) by 1 we get:
3m + 3e = 78 ... (i)
3m + 8e = 123 ... (ii)
Subtracting (ii) - (i) we get;
0m + 5e = 45
5e = 45
e = 45 ÷ 5 = 9
So there are 9 essay questions.
and;
m + 9 = 26
m = 26 - 9 = 17
There are also 17 multiple choice questions.

1/42 * (7(30x+24) - 6(63-7x))
then distribute the multiplication and combine like terms:
= 1/42 * (210x + 168 - 378 +42x)
= 1/42 * (252x-210)

Find the sales tax.
Please also show your work so I can understand it :)
Answers
Explanation: First, you want to do 70(1.05) and get 73.5. The way you get 1.05 is by adding 0.05 (5%) to 1 and get 1.05. Next, you want to do 73.5-70. The reason you should do this is because the number 73.5 is including both the selling price and the sales tax, and the question is asking for just the sales tax. Finally, 73.5-70 is 3.5, AKA your final answer, $3.50. I hope this helped!
Answer:
Sales tax: 3.5$
Total Price: 73.5$
Step-by-step explanation:
the percentage of tax is that much of the total price. if there is 50% sales tax (unrealistic) and the item costs 100 dollars without any tax, then the tax would be 50 dollars. To find this, turn the percent into a decimal (move the decimal place to the left twice) and multiply that by the price. To do this with this problem, use this strategy. 70 times .05= 3.5. Therefore the tax is 3.5$. hope this helps!!

Evan worked 9 hours and
made $85.50. Henry worked 6 hours and made $57.00. Are
these two rates proportional?
Answers
6/9 = 57/85.5
(6*85.5)/9=57, so it’s true.
Answer:
yes both of them make 9.5 the hour I know this because 85.50 divided by 9 is 9.5 9 times 9 is 81 and .5 times 9 is 4.5 so 81+4.5=85.5 and then 57 divided by 6 is 9.5 as well you can do 6 times 9 and you get 54 and then 6 times 0.5 is 3 and 54+3=57

Percentage of people having Lizard = 55% , Percentage of people having both Lizard & Snake = 10%
Important Information : Percentage people having pet snake = 40%
C] Percentage people having pet lizard, along with pet snake = 25% of those having pet snake = 25% of 40% = 10% {Percentage of people having both snake & lizard)
Percentage of people having pet snake only = 75% of those who don't have snake = 75% of ( total - 40%) = 75% of 60% = 45%B] Total percentage of people having pet lizard = 10% + 45% = 55%

Which of the following equations do not represent a proportional relationship? y = 4/3x y = 2x - 1 y = x y = 1.4x
Answers
Answer:
y = 2x - 1
Step-by-step explanation:
y = 2x - 1 wouldn't be a proportional relationship. You can tell because any equation with addition or subtraction is not going to be proportional.
Answer:
y=2x-1
Step-by-step explanation:
notice how the second option, y=2x-1 is the only option that has a constant. All other options only have a coefficient on the x term. This makes it perfectly proportional by the factor of the coefficient.

B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).
C. At approximately x = 4.74, the rate of change of g(x) is equal to the rate of change of f(x).
D. As x increases, the rate of change of f(x) exceeds the rate of change of g(x).
Answers
A statement that is true include the following: B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).
How to determine the average rate of change?In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:
Average rate of change = [f(b) - f(a)]/(b - a)
Next, we would determine the average rate of change of the function f(x) over the interval [0, 1]:
a = 0; f(a) = 1
b = 1; f(b) = 6
By substituting the given parameters into the average rate of change formula, we have the following;
Average rate of change = (6 - 1)/(1 - 0)
Average rate of change = 5/1
Average rate of change = 5
For g(x), we have the following:
Average rate of change = (216 - 0)/(1 - 0)
Average rate of change = 216/1
Average rate of change = 216

4(34)>10 = 136>10 yes
4(2)>10 = 8>10 well no bc 8 is less than 10
4(2.5)>10 = 10 = 10 not 10>10 so no
