1 u + 33

After |
1 u |
1 u + 33 + 48 = 1 u + 81 |
At first, Rael had $15 more than Barbara. After giving to Barbara, he had $81 less than Barbara. This means he gave Barbara more than $15.
Additional amount that Rael gave to Barbara
= (81 - 15) ÷ 2
= 66 ÷ 2
= $33
Total amount that Rael gave to Barbara
= 33 + 15
= $48
Answer(s): $48
