Question

A washer and dryer cost $677 combined. The washer cost $73 less than the dryer. What is the cost to f the dryer

Answer 1

Step-by-step explanation:

Let's assume that the dryer costs x $.

Then the washer costs x-73$, 73$ dollars less.

If we add the two costs together we get that: x+x-73 = 677 <-> 2*x = 750 <-> x=375$

The dryer costs x=375$

Answer 2

Answer:

The cost of the dryer is $375

Step-by-step explanation:

We call w the cost of the washing machine and we call d the cost of the dryer

We know that together they cost $ 677

This means that:

$w + d = 677$

We also know that the washer cost $ 73 less than the dryer

This means that:

$w = d-73$

Now we substitute the second equation in the first and solve for d:

$d-73 + d = 677$

$2d= 677+73$

$2d=750$

$d=\frac{750}{2}$

$d=\ \ 375$
