Answer:
The dryer costs $325.
Step-by-step explanation:
Let <em>w</em> represent the cost of the washer and <em>d</em> represent the cost of the dryer.
They cost $587 combined. In other words:
The washer costs $63 less than the dryer. Therefore:
Thus, we have the system of equations:
We can solve it using substitution. Substitute the second equation into the first. Hence:
Combine like terms:
Add 63 to both sides:
And divide both sides by two. Hence:
The dryer costs $325.
Further Notes:
And since the washer is $63 less, the washer costs:
The washer costs $262.
