Ryan had $46 more than Erika. After Erika spent
17 of her money, Ryan had five times as much money as Erika. How much money did Ryan have at first?
| |
Ryan |
Erika |
| Before |
30 u |
7 u |
| Change |
|
- 1 u |
| After |
30 u |
6 u |
Amount that Ryan had in the end
= 5 x 6 u
= 30 u
If Erika had another $46 at first, the amounts that Ryan and Erika each had at first will be the same.
30 u = 7 u + 46
30 u - 7 u = 46
23 u = 46
1 u = 46 ÷ 23 = 2
Amount Ryan had at first
= 30 u
= 30 x 2
= $60
Answer(s): $60
