18 x 40

1 x 50
= 50¢ |
770¢ |
| 6 |
6 x 40
= 240¢ |
13 |
13 x 50
= 650¢ |
890¢ |
$1 = 100¢
$8.90 = 890¢
Amount paid if all were caramel apples
= 19 x 40
= 760¢
Big difference between the amount paid for the caramel apples and the mochi balls
= 890 - 760
= 130¢
Small difference between the amount paid for the one caramel apple and one mochi ball
= 50 - 40
= 10¢
Number of mochi balls
= 130 ÷ 10
= 13
Answer(s): 13
