Tom |
Zoe |
Before |
1 u + 29 + 28 = 1 u + 57 |
1 u + 29
|
Change |
- 57 |
+ 57 |
After |
1 u |
1 u + 29 + 57 = 1 u + 86 |
At first, Tom had $28 more than Zoe. After giving to Zoe, he had $86 less than Zoe. This means he gave Zoe more than $28.
Additional amount that Tom gave to Zoe
= (86 - 28) ÷ 2
= 58 ÷ 2
= $29
Total amount that Tom gave to Zoe
= 29 + 28
= $57
Answer(s): $57
