- 3 |
| After |
1 u |
1 u + 16 |
Comparing Raeann
and Linda in the end |
1 u |
5 u |
The number of cookies that Raeann had remains unchanged.
Number of cookies that Linda had in the end
= 5 x 1 u
= 5 u
5 u = 1 u + 16
5 u - 1 u = 16
4 u = 16
1 u = 16 ÷ 4 = 4
Number of cookies that Raeann had
= 1 u
= 4
Answer(s): 4
