⦁ A local pizzeria sold 75 pizzas yesterday.
⦁ The owner offers the employees a bonus if the number of pizzas sold increases by 20% today.
⦁ How many pizzas must the pizzeria sell for employees to receive the bonus? Explain your reasoning. Show your work!
⦁ Suppose the actual number of pizzas sold today was 66. Describe the number of pizzas sold as a percent increase or decrease.
Answers
Answer:
a. 90 pizzas
b. 12% decrease
Step-by-step explanation:
To receive a bonus, there must be 20% increase in the number of pizzas
Thus;
20% of 75 = 20/100 * 75 = 1500/100 = 15
So the number of pizza to be sold to receive the bonus will be 15 + 75 = 90
So now, we have 66 pizza sold today;
We can see that there was a decrease from 75
Percentage decrease will be;
(new value - old value)old value * 100%
= (66-75)/75 * 100%
= -9/75 * 100%
= -0.12 * 100% = -12%
This shows a 12% decrease

Julio has 200 ft of fencing to put around a field that has an area of 2500 sq ft. Write an equation that can be used to find the length of
the field?
Answers
Answer:
L = 2500/W
Step-by-step explanation:
Let the fields m be rectangular in nature
Area = LW
Perimeter = 2(L+W)
L is the length
W is the width
Given
Perimeter = 200ft
Area = 2500ft²
Substitute into the formula
200 = 2L+2W
100 = L+W ...... 1
2500 = LW.... 2
From 1; L = 100-W
Substitute into 2
2500 = (100-W)W
100W - W² = 2500
W²-100W+2500 = 0
W²-50W-50W+2500 = 0
W(W-50)-50(W-50) = 0
W - 50 = 0
W =50
Substitute w = 50 into LW = 2500
L = 2500/50
L = 50
Hence the equation that can be used to find the length of the field is
L = 2500/W
a gym is offeringa deal to new members. Customers can sign up by paying a registration fee of $200 and a monthly fee of $39. How much will this membership cost a member by the end of one year?
Answers
Answer:
The answer is $668.00
Step-by-step explanation:
Just add 200 to how much you will pay over time. So first multiply 39 by 12 (12 months in a year, 39 per month,) to find out how much you will pay by the end of the year then add 200 to that.
explanation: there is 12 months in a year, so if you make an equation it would be, 200+39x, input 12 for x making it 200+39(12) 39(12)=468, now you need to add the fee of $200 to 468 making the cost of the membership after one year $668.

In the diagram of AADC below, EB|| DC, ED=60, AB=12, and BC=72. What is the
length of AD?
A
12
E
B
60
72
D
С
Answers
Answer:
The length of AD is 70
Step-by-step explanation:
From the given figure
→ In triangle ADC
∵ EB // to DC
→ That means EB divides the sides AD and AC into parts proportional
∴ E divides AD into AE and ED
∴ B divides AC into AB and BC
∴ [tex]\frac{AE}{ED}[/tex] = [tex]\frac{AB}{BC}[/tex]
∵ ED = 60
∵ AB = 12
∵ BC = 72
→ Substitute them in the ratio above
∴ [tex]\frac{AE}{60}[/tex] = [tex]\frac{12}{72}[/tex]
→ By using cross multiplication
∵ AE × 72 = 12 × 60
∴ 72 AE = 720
→ Divide both sides by 72
∴ AE = 10
∵ AD = AE + ED
∴ AD = 10 + 60
∴ AD = 70
∴ The length of AD is 70

Sofia ordered sushi for a company meeting. They change plans and increase how many people will be at the meeting, so they need at least 100 pieces of sushi in total.
Sofia had already ordered and paid for 24 pieces of sushi, so she needs to order additional sushi. The sushi comes in rolls, and each roll contains 12 pieces and costs $8.
Let R represent the number of additional rolls that Sofia orders.
1) Which inequality describes this scenario?
Choose 1 answer:
A) 12 + 24R ≤ 100
B) 12 + 24R ≥ 100
C) 24 + 12R ≤ 100
D) 24 + 12R ≥ 100
2) What is the least amount of additional money Sofia can spend to get the sushi they need?
dollars
Answers
Answer:
The answer is given below <3
Step-by-step explanation:
The options are not given but I would list the inequalities needed to solve this problem.
As a result of increase in people to attend meeting, the number of sushi needed to be ordered is 100 pieces. Sofia has already ordered 24 pieces. If R is the number of additional rolls that Sofia orders.
The number of additional rolls that Sofia orders (R) must be greater than or equal to the difference between the number of Sushi needed to be ordered and the number of Sushi that has already being ordered. It is given by the inequality:
R ≥ 100 - 24
R ≥ 76
If each roll contains 12 pieces, the number of rolls needed (n) is given by:
n ≥ R/12
n ≥ 76/12
n ≥ 6.33
n ≥ 7
If each roll cost $8, the money needed to buy the sushi is given as:
Cost ≥ 8(7) ≥ $56

what is 20+.25g=22
need step by step explanation
Answers
Answer:
g = 8
Step-by-step explanation:
first move 20 to the right side of the equation by subtracting it. so the equation becomes 0.25g= 22-20 --> 0.25 = 2 and then divide 2 by 0.25 and g will equal 8. you can also plug in 8 for g to check your answer.
Answer:
g = 8
Step-by-step explanation:
First we want to simplify the sides so we will subtract 20 fror each side
.25g =2
then we need to divide each side by .25 to get g isolated or by itself to find the answer
g = 8
If you plug it back into the equation it will be true
20 + (.25 * 8) = 22

Michelle :
(33 /60) * 100% = 55%
Shasha:
(36 /78) * 100% = 46.15%
Kat:
(40 / 89) * 100% = 44.94%
Monica :

0.6(x + 2) = 0.55(2x + 3)
Answers
Answer:
-0.9
Step-by-step explanation:
0.6(x+2)=0.55(2x+3)
Use the distributive property to multiply 0.6 by x+2.
0.6x+1.2=0.55(2x+3)
Use the distributive property to multiply 0.55 by 2x+3.
0.6x+1.2=1.1x+1.65
Subtract 1.1x from both sides.
0.6x+1.2−1.1x=1.65
Combine 0.6x and −1.1x to get −0.5x.
−0.5x+1.2=1.65
Subtract 1.2 from both sides.
−0.5x=1.65−1.2
Subtract 1.2 from 1.65 to get 0.45.
−0.5x=0.45
Divide both sides by −0.5.
x= 0.45/−0.5
x= -0.9
