Total |
| Before |
3 u |
10 u |
|
| Change |
+ $43 |
- $6 |
|
| After |
3 u + $43 |
10 u - $6 |
13 u + $37 |
Amount of money Abi and Xandra has is the same in the end.
10 u - 6 = 3 u + 43
10 u - 3 u = 43 + 6
7 u = 49
1 u = 49 ÷ 7 = 7
Amount the girls have in the end
= 3 u + 43 + 10 u - 6
= 13 u + 37
= 13 x 7 + 37
= 91 + 37
= $128
Answer(s): $128
