4 |
3 |

| Value |
1 u |
1 u + 4 |
|
| Total value |
4 u |
3 u + 12 |
7 u + 12 |
Number of stickers in each packet = 1 u
Number of stickers in each bag = 1 u + 4
Total number of stickers in the packets = 4 x 1 u = 4 u
Total number of stickers in the bags = 3(1 u + 4) = 3 u + 12
Total number of stickers
= 3 u + 4 u + 12
= 7 u + 12
7 u + 12 = 61
7 u = 61 - 12
7 u = 49
1 u = 49 ÷ 7 = 7
Number of stickers in each bag
= 1 u + 4
= 7 + 4
= 11
Answer(s): 11
