Question

a washer and a dryer cosr $873 combined. thenwasher cost$ $77 less than the dryer . what is the cost of the dryer.

Answer 1

Let the dryer cost x.

Then, the washer costs (x-77)

Together, they cost (x) + (x-77) = 873

2x-77 = 873 [subtract 77 from both sides]

2x = 796

x = 398

So the dryer costs $398
