Min and Simon had a total of $268. After Min spent
17 of her money and Simon spent $10, the ratio of Min's money to Kennenth's money became 1 : 6. How much money had Simon at first?

Total |
| Before |
7 u |
36 u + $10 |
$268 |
| Change |
- 1 u |
- $10 |
|
| After |
6 u |
|
|
Comparing Min and
Simon in the end |
1x6 =
6 u |
6x6 =
36 u |
|
The amount that Min had in the end is repeated. Make the amount that Min had in the end the same. LCM of 6 and 1 is 6.
Total amount that Min and Simon had at first
= 7 u + 36 u + 10
= 43 u + 10
43 u + 10 = 268
43 u = 268 - 10
43 u = 258
1 u = 258 ÷ 43 = 6
Amount that Simon had at first
= 36 u + 10
= 36 x 6 + 10
= 216 + 10
= $226
Answer(s): $226
