1 x 70

770¢ |
| 4 |
4 x 50
= 200¢ |
11 |
11 x 70
= 770¢ |
970¢ |
$1 = 100¢
$9.70 = 970¢
Amount paid if all were mini cupcakes
= 15 x 50
= 750¢
Big difference between the amount paid for the mini cupcakes and the candy canes
= 970 - 750
= 220¢
Small difference between the amount paid for the one mini cupcake and one candy cane
= 70 - 50
= 20¢
Number of candy canes
= 220 ÷ 20
= 11
