TSI Math Test Preperation With Answers

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?: 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.
2. What is the formula for Area?: 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?: 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?: Martina's
age ten years ago is:
m 10

So Diego's age is:
5(m 10)
= 5m 50
5. The variables x and y are directly proportional, and y = 2 when x = 3. What
is the value of y when x = 9?: Y= K*X
2= K*3
2/3 = K*3 /3
1/3
