during the first week of a going out of business sale, Sam's general store reduces all prices by 10%. The second week of the sale, Sam's reduces all items by an additional $5. If jim COndor bought a calculator for $49 during the second week of the sale, find the original price of the calculator. How can i put this in a equation? i know the answer is 60.

Let us take the original price of a calculator in store be x.
Now as the price got reduced by 10% in the first week, therefore the price in the first week will be x – 10%x = x ( 1 – 10/100) = x (90/100) = .9x
In the second week price got reduced by $ 5 from the prices of first week, so the price will be .9x – 5
The calculator was bought in the second week, it implies .9x – 5 = 49
.9x – 5 = 49
.9x = 49 + 5
.9x = 54
x = 54 / .9
x = 60
so, the original price of calculator will be $60.
