A couch and coffee table cost a total of $980. The cost of the couch is three times the cost of the coffee table. Find the cost of each item.

Answer 1

k + t = 980

k = 3t

substitute 2nd value for k into 1st equation

3t + t = 980

4t = 980

t = 980/4

t = $245 = cost of the coffee table

k = 980-245 = $735 = cost of the couch
