Could you help me solve this math problem?

A hardware store stocks two types of hammers. The store has a total of 42 hammers, with sledge hammers selling at $22.95 each and claw hammers selling at $10.95 each. If the total value of the hammers is $639.90, how many of each type are in stock?


Best Answer...

Answer:

let x = number of sledge hammers
let y = number of claw hammers

x+y=42
22.95x+10.95y=639.9

x=42-y
22.95(42-y)+10.95y=639.9
963.9-22.95y+10.95y=639.9
324=12y
27=y
15=x
