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
4.22 x 1.0875 = 4.589
4.589 is rounded to 4.59
So the answer is correct

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
