|
Reggie |
Gem |
Before |
1 u + 30 + 12 = 1 u + 42 |
1 u + 30
|
Change |
- 42 |
+ 42 |
After |
1 u |
1 u + 30 + 42 = 1 u + 72 |
At first, Reggie had $12 more than Gem. After giving to Gem, he had $72 less than Gem. This means he gave Gem more than $12.
Additional amount that Reggie gave to Gem
= (72 - 12) ÷ 2
= 60 ÷ 2
= $30
Total amount that Reggie gave to Gem
= 30 + 12
= $42
Answer(s): $42
