2 |
6 |

| Value |
1 u |
1 u + 7 |
|
| Total value |
2 u |
6 u + 42 |
8 u + 42 |
Number of stickers in each bag = 1 u
Number of stickers in each packet = 1 u + 7
Total number of stickers in the bags = 2 x 1 u = 2 u
Total number of stickers in the packets = 6(1 u + 7) = 6 u + 42
Total number of stickers
= 6 u + 2 u + 42
= 8 u + 42
8 u + 42 = 186
8 u = 186 - 42
8 u = 144
1 u = 144 ÷ 8 = 18
Number of stickers in each packet
= 1 u + 7
= 18 + 7
= 25
Answer(s): 25
