Answer 8

Let w equal the cost of a washing machine.

Since there are 11 washing machines we have this:

11w +cost of the dryers = total cost of both machines

We are given that the cost of dryer is the same as the cost of a washing machine, and eight dryers where purchased.

So the cost of the dryers is 8w

So our equation looks like this:

11w + 8w = total cost of the both machines

We are given that the total cost of both machines is $10,450

So our equation looks like this:

11w + 8w = 10,450

Solve for w.

19w=10,450
w=10,450/19
w=550

So the cost per machine is $550
