The required amount is $79.99.
Step-by-step explanation:
Given : 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).
To find : How much change would he receive from a $100 bill?
Solution :
A customer buys 17.01 in gas.
Request for
One five dollar [$5] lottery ticket = $5
Two one dollar [$1] lottery tickets = $2
One [$3] lottery ticket = $3.
Total amount he spend = $17.01+$5+$2+$3=$27.01.
He gives you two winning tickets to be redeemed: one for ($5) and the other for ($2) i.e. $5+$2=$7
So, Amount he spend is $27.01-$7=$20.01
If he receives change from a $100 bill,
Then the required amount is $100-$20.01=$79.99.
