Question

a customer buys 17.01 in gas and requests one five dollar lottery ticket, two one dollar lottery tickets, and one three dollar 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?

Answer 1

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
