1 u + 27

After |
1 u |
1 u + 27 + 46 = 1 u + 73 |
At first, John had $19 more than Opal. After giving to Opal, he had $73 less than Opal. This means he gave Opal more than $19.
Additional amount that John gave to Opal
= (73 - 19) ÷ 2
= 54 ÷ 2
= $27
Total amount that John gave to Opal
= 27 + 19
= $46
Answer(s): $46
