Answer:

$505

Step-by-step explanation:

930 - 80 = 850

850 / 2 = 425 (price of the washer)

425 + 80 = 505 (price of the dryer)

Answer:

the dryer costs $425

Step-by-step explanation:

x = washer

y = dryer

x + y = 930

x = y + 80

using the second equation as substitute in the first equation we get

y + 80 + y = 930

2y = 850

y = $425

FYI

x = y + 80 = 425 + 80 = $505
