Chris wants to order dvds over the internet each dvd costs $14.50 and shopping for the entire order is $7.20 if chris has $100 to spend what is the greatest number of dvds can chris order"

If Chris only has $100 to spend and the order itself is $7.20, that already leaves him with only $92.80 left. The maximum amount of DVDs he can be with that amount is 6, which would cost $87. Combining that with the $7.20 he has to pay, that makes $94.20. Therefore, he can buy 6 DVDs without going above $100.
