A customer buys 17.01 in gas and requests one five dollar $5 lottery ticket, two one dollar $1 lottery tickets, and one $3 lottery ticket. He gives you two winning tickets to be redeemed: one for $5 and the other for $2. How much change would he receive from a $100 bill?

The customer gave you:
-- $100
-- $5 winning ticket
-- $2 winning ticket
Total . . . $107

You gave the customer:
-- $17.01 in the form of gas
-- $5 in the form of a $5 lottery ticket
-- $2 in the form of two $1 lottery tickets
-- $3 in the form of a $3 lottery ticket
Total . . . $27.01

In order to be even, you must give the customer another 

             ($107 - $27.01) = $79.99  in change

He would receive $79.99 in change. 

First, you should add together what he's spending:

17.01 + 5 + 1 + 1 + 3 = 27.01.

This is the total that he owes. Now, you should add together the winning tickets:

5 + 2 = 7.

Since he owes $27.01 and won $7, you should subtract 7 from his total:

27.01 - 7 = 20.01.

This is now his total. If he receives change from a $100 bill, then you subtract the total from 100:

100 - 20.01 = 79.99.
