At Frameworks Hardware Store's 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 Father's Day. Each drill set cost $25 less than its full price. She paid a total of $86.
write an equation you can use to find f, the cost of each drill set at full price?

Answer 1

Assuming f to be the cost of the drill set at full price,

The equation which will represent this is

2( f- 25) = 862(f−25)=86

Solve for f to get

2f - 50 = 862f−50=86

2f = 1362f=136

f = 68f=68

The cost of the drill set at full price is $68.
