Answer:
the dryer costs $450
step-by-step explanation:
w + d = 831
w = d-69 (they told us we will have to take $69 from the cost of the dryer to determine the cost of the washer)
(d-69) + d = 831
Let's combine like terms
2d - 69 = 831
add 69 to both sides to solve for d
2d = 900
divide both sides by 2 to solve for d
d = 450; the dryer costs $450
The answer is 171.25.
