Caden had $60 more than Ivory. After Ivory spent
29 of her money, Caden had thrice as much money as Ivory. How much money did Caden have at first?
| |
Caden |
Ivory |
| Before |
21 u |
9 u |
| Change |
|
- 2 u |
| After |
21 u |
7 u |
Amount that Caden had in the end
= 3 x 7 u
= 21 u
If Ivory had another $60 at first, the amounts that Caden and Ivory each had at first will be the same.
21 u = 9 u + 60
21 u - 9 u = 60
12 u = 60
1 u = 60 ÷ 12 = 5
Amount Caden had at first
= 21 u
= 21 x 5
= $105
Answer(s): $105
