$40
40*90/100 = 36
You just have to be careful with the rest of the problem
Answer:
If you were trying to find 15% of 18, that would be multiplying a decimal, but, you need to mutliply a whole number. $120 should be your answer. People, correct me if I'm wrong (seriously though, not 100% sure if this is correct).
Step-by-step explanation:
18 = 15% x Y
18 = 15/100 x Y
Y = 18 × 100/15
Y = 18 × 100 ÷ 15
Y = 120

Are you trying to find x, or are you only suppose to translate it?
If you are trying to find x, you first multiply 2x on both sides
100 = 10(2x)
Divide 10 on both sides
10 = 2x
Divide 2 on both sides
5 = x
