|
Rael |
Penelope |
Before |
1 u + 35 + 21 = 1 u + 56 |
1 u + 35
|
Change |
- 56 |
+ 56 |
After |
1 u |
1 u + 35 + 56 = 1 u + 91 |
At first, Rael had $21 more than Penelope. After giving to Penelope, he had $91 less than Penelope. This means he gave Penelope more than $21.
Additional amount that Rael gave to Penelope
= (91 - 21) ÷ 2
= 70 ÷ 2
= $35
Total amount that Rael gave to Penelope
= 35 + 21
= $56
Answer(s): $56
