Japheth |
Mary |

1 u + 21 + 11 = 1 u + 32 |
1 u + 21
|
Change |
- 32 |
+ 32 |
After |
1 u |
1 u + 21 + 32 = 1 u + 53 |
At first, Japheth had $11 more than Mary. After giving to Mary, he had $53 less than Mary. This means he gave Mary more than $11.
Additional amount that Japheth gave to Mary
= (53 - 11) ÷ 2
= 42 ÷ 2
= $21
Total amount that Japheth gave to Mary
= 21 + 11
= $32
Answer(s): $32
