Question

Maria spent 36% of her savings to buy a smart phone. The phone cost $90. How much money was in Maria’s savings account before she purchased the phone? Find the unknown value. 36% =90

Answer 1

$250

Explanation:

convert 36% to a decimal by dividing by 100

36/100 = .36

Now setup the equation. The problem say 36% of her savings. "Of" means multiply and we don't know how much she had in savings, so this will be our variable, x.

.36x = 90

Divide by .36

.36x/.36 = 90/.36

x = 250
