TSI Math Test Preperation|Latest Update Graded A+
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.


What is the formula for Area?
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?
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?
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?
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
