1 u |
1 u + 8 |
|
| Total value |
6 u |
2 u + 16 |
8 u + 16 |
Number of stamps in each packet = 1 u
Number of stamps in each box = 1 u + 8
Total number of stamps in the packets = 6 x 1 u = 6 u
Total number of stamps in the boxes = 2(1 u + 8) = 2 u + 16
Total number of stamps
= 2 u + 6 u + 16
= 8 u + 16
8 u + 16 = 120
8 u = 120 - 16
8 u = 104
1 u = 104 ÷ 8 = 13
Number of stamps in each box
= 1 u + 8
= 13 + 8
= 21
Answer(s): 21
