203 - 4 =
199 |

7 x 4 =
28 |
161 - 28 =
133 |
Total number of packets of caramel apples if all are caramel apples
= 30 x 7
= 210
Big difference between the total number of caramel apples and mochi balls
= 210 - 133
= 77
Small difference between the number of caramel apples in one packet and the number of mochi balls in one bag
= 210 - 199
= 11
Number of bags of mochi balls
= 77 ÷ 11
= 7
Answer(s): 7
