30 x 6 =
180 |

180 - 0 =
180 |
29
|
29 x 6 =
174 |
1
|
1 x 4 =
4 |
174 - 4 =
170 |
22
|
22 x 6 =
132 |
8

8 x 4 =
32 |
132 - 32 =
100 |
Total number of packets of mochi balls if all are mochi balls
= 30 x 6
= 180
Big difference between the total number of mochi balls and mini cupcakes
= 180 - 100
= 80
Small difference between the number of mochi balls in one packet and the number of mini cupcakes in one bag
= 180 - 170
= 10
Number of bags of mini cupcakes
= 80 ÷ 10
= 8
Answer(s): 8
