All you have to do is find 40% or .4 of 90.
90 x .4 = 36
36$ is the mark up, so the total price would be 126$.
Answer:
$126
Step-by-step explanation:
First, use the general percent equation (y is x% of z, y being your part percentage, x being your percent, and z being your whole base).
y = 40% x 90 --> .4 x 90 = 36
y = 36
Now, simply add the part percentage (36) to the original whole base.
90 + 36 = 126
