Question

A washer and a dryer cost $708 combined. The washer costs $58 more than the dryer. What is the cost of the dryer?

Answer 1

$325

Explanation:

Let x be the price of the washer.

Let y be the price of the dryer.

x + y = 708

x = y + 58

Put x as y+58 in the first equation and solve for y.

y + 58 + y = 708

2y + 58 = 708

2y = 650

y = 650/2

y = 325

Put y as 325 in the second equation and solve for x.

x = 325 + 58

x = 383

The cost of the washer is $383.

The cost of the dryer is $325.

Answer 2

Explanation:

Cost of dryer = $ d

Cost of washer = d + 58

Total cost = $ 708

d + (d + 58) = 708

2d + 58 = 708

2d = 708 - 58

2d = 650

d = 650/2

d = 325

Cost of washer = 325 + 58 = $ 383

Cost of dryer = $ 325
