John has 3 bedroom doors and two outside doors to replace. The outside doors cost $20 each to replace and the bedroom doors are half that cost. How much does he pay in total?
A step-by-step solution is:
70
The outside doors cost 2 * $20 = $40.

Each indoor door cost $20 / 2 = $10.

So all the indoor doors cost $10 * 3 = $30.

That means the total cost is $40 + $30 = $70.

.

Therefore, the answer is 70
