8 x 60
= 480¢ |

4 x 70
= 280¢ |
760¢ |
$1 = 100¢
$7.60 = 760¢
Amount paid if all were candy canes
= 12 x 60
= 720¢
Big difference between the amount paid for the candy canes and the mochi balls
= 760 - 720
= 40¢
Small difference between the amount paid for the one candy cane and one mochi ball
= 70 - 60
= 10¢
Number of mochi balls
= 40 ÷ 10
= 4
