17 x 40

1 x 60

740¢ |
| 5 |
5 x 40
= 200¢ |
13 |
13 x 60
= 780¢ |
980¢ |
$1 = 100¢
$9.80 = 980¢
Amount paid if all were candy canes
= 18 x 40
= 720¢
Big difference between the amount paid for the candy canes and the mini cupcakes
= 980 - 720
= 260¢
Small difference between the amount paid for the one candy cane and one mini cupcake
= 60 - 40
= 20¢
Number of mini cupcakes
= 260 ÷ 20
= 13
