Janet makes homemade dolls. Currently, she produces 23 dolls per month. If she increased her
production by 18%, how many dolls would Janet produce each month?
- correct answer First, calculate 18% of 23.

23 × 0.18 = 4.14

Then, add this value (the increase) to the original value of 23.

23 + 4.14 = 27.14

Rounding off, we get 27.



What is the formula for Area?
- correct answer Area = L*W



Bill's new porch is rectangular, with an area of 50 square feet. If the length of the porch is two times the
width, what is the perimeter of the porch?
- correct answer The formula for the area of a rectangle:



A = Width * Length



From the question we know that L = 2W and that A = 50. So we can plug these values into our equation
and solve for W:



50 = W * L

50 = W * 2W

50 = 2W²

W² = 25

, W=5



We know that L = 2W, so L = 10

Perimeter = 2L + 2W

Perimeter = 2 * 10 + 2 * 5

Perimeter = 30



Diego's current age is five times Martina's age ten years ago. If Martina is currently m years old, what is
Diego's current age in terms of m?
- correct answer Martina's age ten years ago is:

m − 10



So Diego's age is:

5(m − 10)

= 5m − 50



The variables x and y are directly proportional, and y = 2 when x = 3. What is the value of y when x = 9?
- correct answer Y= K*X

2= K*3

2/3 = K*3 /3

K = 2/3

Plug in K for the second formula

Y=2/3(9)

Y = 2*3 = 6

The correct answer is 6



The yard behind Cindy's house is rectangular in shape and has a perimeter of 72 feet. If the length L of
the yard is 18 feet longer than the width W of the yard, what is the area of the yard, in square feet?
- correct answer Area= L*W

Perimeter= 2l + 2w
