Yasmin bought several items at the discount store. She paid 8.75 percent sales tax, an amount of $4.59, on the total amount of her purchase. What was the total amount of her purchase before tax was added?
The equation is x(1.0875)=$4.59 The x is the original price So multiplying by 1.0875 will result you into the price after tax which is 4.59 So your goal is to get x by itself ( x=..... ) to find the original price before tax In this problem, x is being multiplied by the tax ( 1.0875 ) So to get it alone you have to divide it by 1.0875 What you do one side you have to do to the other side So your equation ended up like x = 4.22 So the original price is $4.22
To check your answer: 4.22 x 1.0875 = 4.589 4.589 is rounded to 4.59 So the answer is correct
