1 u + 17 |
| Change |
|
- 5 |
| After |
1 u |
1 u + 12 |
Comparing Diana
and Roshel in the end |
1 u |
5 u |
The number of macarons that Diana had remains unchanged.
Number of macarons that Roshel had in the end
= 5 x 1 u
= 5 u
5 u = 1 u + 12
5 u - 1 u = 12
4 u = 12
1 u = 12 ÷ 4 = 3
Number of macarons that Diana had
= 1 u
= 3
