Ivan had $35 more than Xandra. After Xandra spent
19 of her money, Ivan had twice as much money as Xandra. How much money did Ivan have at first?
| |
Ivan |
Xandra |
| Before |
16 u |
9 u |
| Change |
|
- 1 u |
| After |
16 u |
8 u |
Amount that Ivan had in the end
= 2 x 8 u
= 16 u
If Xandra had another $35 at first, the amounts that Ivan and Xandra each had at first will be the same.
16 u = 9 u + 35
16 u - 9 u = 35
7 u = 35
1 u = 35 ÷ 7 = 5
Amount Ivan had at first
= 16 u
= 16 x 5
= $80
Answer(s): $80
