|
Henry |
Zoe |
Before |
1 u + 30 + 20 = 1 u + 50 |
1 u + 30
|
Change |
- 50 |
+ 50 |
After |
1 u |
1 u + 30 + 50 = 1 u + 80 |
At first, Henry had $20 more than Zoe. After giving to Zoe, he had $80 less than Zoe. This means he gave Zoe more than $20.
Additional amount that Henry gave to Zoe
= (80 - 20) ÷ 2
= 60 ÷ 2
= $30
Total amount that Henry gave to Zoe
= 30 + 20
= $50
Answer(s): $50
