| 8 |
8 x 50
= 400¢ |

760¢ |
$1 = 100¢
$7.60 = 760¢
Amount paid if all were candy canes
= 12 x 50
= 600¢
Big difference between the amount paid for the candy canes and the sweets
= 760 - 600
= 160¢
Small difference between the amount paid for the one candy cane and one sweet
= 90 - 50
= 40¢
Number of sweets
= 160 ÷ 40
= 4
