SAT Math Question for the week of 10/31/2021

A candy store has reduced the original price of all the chocolate boxes by 10%. Ela bought one box of chocolates at the discounted price and paid $11.34 after addition of 5% sales tax. What was the original price, in dollars, of the box of chocolates Ela bought, excluding the sales tax?

Maps to Category 46 of my book.

Convert all the percentages to decimal.

10% reduction = 0.9.

5% sales tax = 1.05.


To determine the original price, divide the end price (price paid) by the above decimals.

11.34/(0.9x1.05) = 12
