Tim had $33 more than Barbara. After Barbara spent
27 of her money, Tim had twice as much money as Barbara. How much money did Tim have at first?
| |
Tim |
Barbara |
| Before |
10 u |
7 u |
| Change |
|
- 2 u |
| After |
10 u |
5 u |
Amount that Tim had in the end
= 2 x 5 u
= 10 u
If Barbara had another $33 at first, the amounts that Tim and Barbara each had at first will be the same.
10 u = 7 u + 33
10 u - 7 u = 33
3 u = 33
1 u = 33 ÷ 3 = 11
Amount Tim had at first
= 10 u
= 10 x 11
= $110
Answer(s): $110
