| 12 |
12 x 40

4 x 90
= 360¢ |
840¢ |
$1 = 100¢
$8.40 = 840¢
Amount paid if all were mochi balls
= 16 x 40
= 640¢
Big difference between the amount paid for the mochi balls and the candy canes
= 840 - 640
= 200¢
Small difference between the amount paid for the one mochi ball and one candy cane
= 90 - 40
= 50¢
Number of candy canes
= 200 ÷ 50
= 4
