Tom |
Tina |
Before |
1 u + 17 + 13 = 1 u + 30 |
1 u + 17
|
Change |
- 30 |
+ 30 |
After |
1 u |
1 u + 17 + 30 = 1 u + 47 |
At first, Tom had $13 more than Tina. After giving to Tina, he had $47 less than Tina. This means he gave Tina more than $13.
Additional amount that Tom gave to Tina
= (47 - 13) ÷ 2
= 34 ÷ 2
= $17
Total amount that Tom gave to Tina
= 17 + 13
= $30
Answer(s): $30
