11 x 60
= 660¢ |

1 x 90
= 90¢ |
750¢ |
| 4 |
4 x 60
= 240¢ |
8 |
8 x 90
= 720¢ |
960¢ |
$1 = 100¢
$9.60 = 960¢
Amount paid if all were lollipops
= 12 x 60
= 720¢
Big difference between the amount paid for the lollipops and the mini cupcakes
= 960 - 720
= 240¢
Small difference between the amount paid for the one lollipop and one mini cupcake
= 90 - 60
= 30¢
Number of mini cupcakes
= 240 ÷ 30
= 8
Answer(s): 8
