Tina and Daniel had a total of $137. After Tina spent
18 of her money and Daniel spent $5, the ratio of Tina's money to Kennenth's money became 1 : 2. How much money had Daniel at first?
| |
Tina |
Daniel |
Total |
| Before |
8 u |
14 u + $5 |
$137 |
| Change |
- 1 u |
- $5 |
|
| After |
7 u |
|
|
Comparing Tina and
Daniel in the end |
1x7 =
7 u |
2x7 =
14 u |
|
The amount that Tina had in the end is repeated. Make the amount that Tina had in the end the same. LCM of 7 and 1 is 7.
Total amount that Tina and Daniel had at first
= 8 u + 14 u + 5
= 22 u + 5
22 u + 5 = 137
22 u = 137 - 5
22 u = 132
1 u = 132 ÷ 22 = 6
Amount that Daniel had at first
= 14 u + 5
= 14 x 6 + 5
= 84 + 5
= $89
Answer(s): $89
