7 x 50
= 350¢ |

710¢ |
$1 = 100¢
$7.10 = 710¢
Amount paid if all were mini cupcakes
= 11 x 50
= 550¢
Big difference between the amount paid for the mini cupcakes and the candy canes
= 710 - 550
= 160¢
Small difference between the amount paid for the one mini cupcake and one candy cane
= 90 - 50
= 40¢
Number of candy canes
= 160 ÷ 40
= 4
