| Value |
1 u |
1 u + 5 |
|
| Total value |
4 u |
5 u + 25 |
9 u + 25 |
Number of stickers in each bag = 1 u
Number of stickers in each box = 1 u + 5
Total number of stickers in the bags = 4 x 1 u = 4 u
Total number of stickers in the boxes = 5(1 u + 5) = 5 u + 25
Total number of stickers
= 5 u + 4 u + 25
= 9 u + 25
9 u + 25 = 79
9 u = 79 - 25
9 u = 54
1 u = 54 ÷ 9 = 6
Number of stickers in each box
= 1 u + 5
= 6 + 5
= 11
Answer(s): 11
