The cost of the desk was five times the cost of the chair. The total cost of both the desk and chair was $720.

Question

How do you solve for the answer? 

 

a. $50

b. $120

c. $100

d. $220

Answer 1

You have not really asked the question--you just stated the given facts.

From these facts you can write the equation, after you let c = chair's cost, so desk's cost must be 5c.

 

c + 5c = 720.

 

Solve for c and you will determine the cost of the chair, and then you can also know the cost of the desk.
