1 u + 27

+ 45 |
After |
1 u |
1 u + 27 + 45 = 1 u + 72 |
At first, Ryan had $18 more than Penelope. After giving to Penelope, he had $72 less than Penelope. This means he gave Penelope more than $18.
Additional amount that Ryan gave to Penelope
= (72 - 18) ÷ 2
= 54 ÷ 2
= $27
Total amount that Ryan gave to Penelope
= 27 + 18
= $45
Answer(s): $45
