Question

Nancy bought 2 packs of Digimon cards for $3.07 each, and a deck of baseball cards for $10.36 with a $20 bill. What was the change from the purchase?

Answer 1

cost = 2*3.07+10.36

cost = 6.14+10.36

cost =16.50

20-16.50=change

3.50

She will get $3.50 change

Answer 2

3.07 × 2 = 6.14
6.14 + 10.36 = 16.5
20 - 16.5 = 3.5
3.5 + 7.88 = 11.38
Nancy should get $3.50 back
with the extras, you she should have $11.38
