| 10 |
10 x 40
= 400¢ |

8 x 60
= 480¢ |
880¢ |
$1 = 100¢
$8.80 = 880¢
Amount paid if all were mochi balls
= 18 x 40
= 720¢
Big difference between the amount paid for the mochi balls and the candy canes
= 880 - 720
= 160¢
Small difference between the amount paid for the one mochi ball and one candy cane
= 60 - 40
= 20¢
Number of candy canes
= 160 ÷ 20
= 8
