20 x 40

1 x 50
= 50¢ |
850¢ |
| 7 |
7 x 40
= 280¢ |
14 |
14 x 50
= 700¢ |
980¢ |
$1 = 100¢
$9.80 = 980¢
Amount paid if all were mochi balls
= 21 x 40
= 840¢
Big difference between the amount paid for the mochi balls and the candy canes
= 980 - 840
= 140¢
Small difference between the amount paid for the one mochi ball and one candy cane
= 50 - 40
= 10¢
Number of candy canes
= 140 ÷ 10
= 14
