Answer and explanation:
To determine number if DVDs that can be bought for $20, we simply check price per DVD then calculate how many $20 can buy
Number of DVDs that can be rented for no more than $20
=$20 divided by cost of each DVD $3.50
=20/3.50
=5.714
=5 DVDs
We round down because 0.714 DVD does not qualify as one DVD
