2 |
5 |

| Value |
1 u |
1 u + 4 |
|
| Total value |
2 u |
5 u + 20 |
7 u + 20 |
Number of stickers in each packet = 1 u
Number of stickers in each box = 1 u + 4
Total number of stickers in the packets = 2 x 1 u = 2 u
Total number of stickers in the boxes = 5(1 u + 4) = 5 u + 20
Total number of stickers
= 5 u + 2 u + 20
= 7 u + 20
7 u + 20 = 132
7 u = 132 - 20
7 u = 112
1 u = 112 ÷ 7 = 16
Number of stickers in each box
= 1 u + 4
= 16 + 4
= 20
Answer(s): 20
