Question

at frameworks hardware stores annual start-of-summer sale, every drill set in the shop gets marked down. arianna purchased 2 drill sets during the sale: one for herself and one to give her grandpa on fathers day. each drill set cost $25 less than its full price. she paid a total of $86. which equation can you use to find f, the cost of each drill set at full price? 25(f - 2) = 86 2(f - 25) = 86 2f - 25 = 86 25f - 2 = 86

Explanation:

Step1: Define sale price per set

The sale price of one drill set is full price minus $25, so it is $f - 25$.

Step2: Set up total cost equation

Arianna bought 2 sets, total cost is 2 times the sale price, equal to $86.
$2(f - 25) = 86$

Answer:

2(f - 25) = 86
