1. 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?
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 ott, we get 27.
2. What is the formula for Area?
Answer: Area = L*W
3. 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?
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
4. 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?
Answer: Martina's age ten years ago is
m − 10
