1 u + 39 + 61 = 1 u + 100 |
At first, Bobby had $22 more than Emily. After giving to Emily, he had $100 less than Emily. This means he gave Emily more than $22.
Additional amount that Bobby gave to Emily
= (100 - 22) ÷ 2
= 78 ÷ 2
= $39
Total amount that Bobby gave to Emily
= 39 + 22
= $61
Answer(s): $61
