A bookkeeper needs to post the cost of a desk and chair into his records. The cost of the desk was five times the cost of the chair. The total cost of both the desk and chair was $720. What was the cost of the chair?

Respuesta :


Form an equation;
let c= chair and d=desk

d= 5 x chair
720= c + d

Rewrite the equation in terms of chair

c + 5c = 720
6c = 720
c = 120

Check: 120+ (5x120) = 720
120+ 600 = 720

Answer: im guessing its 120
