Kylie and Harry had a total of $125. After Kylie spent
58 of her money and Harry spent $6, the ratio of Kylie's money to Kennenth's money became 1 : 3. How much money had Harry at first?
| |
Kylie |
Harry |
Total |
| Before |
8 u |
9 u + $6 |
$125 |
| Change |
- 5 u |
- $6 |
|
| After |
3 u |
|
|
Comparing Kylie and
Harry in the end |
1x3 =
3 u |
3x3 =
9 u |
|
The amount that Kylie had in the end is repeated. Make the amount that Kylie had in the end the same. LCM of 3 and 1 is 3.
Total amount that Kylie and Harry had at first
= 8 u + 9 u + 6
= 17 u + 6
17 u + 6 = 125
17 u = 125 - 6
17 u = 119
1 u = 119 ÷ 17 = 7
Amount that Harry had at first
= 9 u + 6
= 9 x 7 + 6
= 63 + 6
= $69
Answer(s): $69
