Ryan |
Nick |
| Before |
12 u |
1 u |
| Change |
- 4 u |
|
| After |
8 u |
1 u |
Amount that Ryan had after he spent one-third of his money
= 12 u ÷ 3
= 4 u
Amount that Ryan had more than Nick in the end
= 8 u - 1 u
= 7 u
7 u = 21
1 u = 21 ÷ 7 = 3
Amount that Ryan had at first
= 12 u
= 12 x 21
= $252
Answer(s): $252
