Carl bought 19 apples of 2 different varieties to make a pie. The total cost of the apples was $5.10. Granny Smith apples cost $0.25 each and Gala apples cost $0.30 each. How many of each type of apple did Carl buy?

Answers

Answer 1

Answer:

Step-by-step explanation:

Split 19 into 2, since Carl bought two types of apples.

19/2 = 9.5

0.25 x 9 = 2.25

0.3 x 9 = 2.7

2.25 + 2.7 = 4.95

5.10 - 4.95 = 0.15

0.3 x 8 = 2.4

2.25 + 2.4 = 4.65

5.1 - 4.65 = 0.45

Find the total cost with tip.

Markup (tip $) = percent markup (tip %) x original cost ($)

Total cost = original cost + tip


Mr. Smith goes out to eat for his birthday. The total bill is $122.50. If Mr. Smith leaves a 20% tip, what is the tip amount? What is the total cost of the meal with tip included?

The tip is: $_________

The total cost of the meal is: $_________

Answers

Answer:

$147

Step-by-step explanation:

so to find 20% I usually divide the original cost by 100 to get 1% then multiply that number by 20.

in this case 122.50/100= 1.225, 1.225x20 = 24.5

24.5 + 122.50 = 147

c. 19.75 is about 20, and 20 multiplied by 5 is 100

Answers

Answer:

you answer is 1,090

Step-by-step explanation:

part is ,327

of whole,x

percent,30

327over x = 30 over 100

327*100=30x

32700=30x

÷30-÷30

= 1090x

do 1090 8s the overall answer

ANSWER: $425.10

The mark down is 30% so we need to find how much that is then add it to the price it is now.

30% of 327 = 98.1

So now we need to add 98.1 to 327

98.1 + 327 = 425.10

Courtney has $21.50 to buy a gift for her brother. She found a stuffed animal that costs $19.65. With 10.1% sales tax added on, what is the sales tax? What is the total cost of the stuffed animal with tax included? Will Courtney have enough money to buy the gift?

The sales tax is: $_________

The total cost is: $_________

Is it enough money?

Answers

Answer:

Sales tax: 1.98465 which in this case is $1.98 (take note that you can round and it would be $2)

The total cost: $21.63 so no, Courtney cant buy the stuffed animal :(

Step-by-step explanation:

You can find the sales tax by dividing 10.1 by 100 to get 1.984...then rounding that number to get $1.98 since we are working with money in this problem then we have to find the total cost by adding our sales tax ($1.98) to our original cost ($19.65) to get our FINAL answer of $21.63

Question 1
A truck driver drove 48 miles in 45 minutes. At this rate, how many miles can the truck driver drive in one hour?



__ miles in one hour
pls no links ty

Answers

The truck driver can drive 64 miles in one hour.

Distance covered by the truck driver in 45 minutes = 48 miles

Distance covered by the truck driver in 1 minute = [tex]\frac{48}{45}[/tex]

                                                                                 = 1.066 miles

Distance covered by the truck driver in 1 hour i.e. 60 minutes = 60 × 1.066

                                                                                                      = 63.96

                                                                                                      ≈ 64 miles

Therefore, the distance covered by the truck driver in 1 hour is 64 miles.

Jose goes out to lunch. The bill, before tax and tip, was $10.45. A sales tax of 8% was added on. Jose tipped 17% on the amount after the sales tax was added. What was the total cost of the meal, plus tax and tip? Round to the nearest cent.

Answers

$13.20 $10.45x1.08=$11.28 $11.28x1.17=$13.20
ANSWER: $13.21

Find 8% of 10.45 then add the answer to 10.45 to get how much it cost after the sales tax.

8% of 10.45 = 0.836

Add 0.84 to 10.45

The answer is 11.29

Now take 17% of 11.29 and add it to 11.29. We are taking 17% of 11.29 because it said he tipped after the sales tax was added.

17% of 11.29 = 1.92

11.29 + 1.92 = 13.21

Question about finding intercepts from a table. Hope someone can answer!

Answers

Basically you have to use the table to find the equation of the line, then plug in a point into x and y and the b you will get is your y-intercept.

Now if you are familiar with the equation of a line in slope intercept form, it will look like this: y=mx+b. Here the ‘m’ is the slope and the ‘b’ is your y-intercept. What you need to do is use any two points given from the table and find the slope. To do that follow the steps below:

1. Pick two points. Let’s take the first two.
(-28, -54) And (-21, -40)

2. Subtract the two y values, -40 - (-54) = 14
3. Subtract the two x values, -21 - (-28) = 7
4. Now take your answer from step 2 and divide it by your answer in step 3. This will be 14/7, which will be 2.

Your answer from step 4 is your slope, or ‘m’.
(That series of steps was basically change in y over change in x, you can look that up if you are still confused)

Now that you know m, your incomplete equation will be this:
y=2x+b.

Next you will pick any point from the table again, and replace it with x and y in the equation. Let’s pick the second point, (-21,-40)

Plug this in: -40 = 2(-21) + b
Solve for b and you will get your answer.
-40 = -42 + b
b=2
Your answer is 2, that is the y intercept.
(The full equation of the line from that table would be y=2x+2)

The answer would be 1. This is because if you do this equation for every row in the table it would always equal y. 1/2x (x divided by 2) would always equal 2 less than y. There is no unit rate in this problem because it is not proportional.
