Answer: 300
1 year of tution and college fee: $9,500
= $9,500 × 2 = $19,000
2 years of tution and college fee: $19,000
Money already in Account = $5,000
If we deposit $100 every month for 5 years we would get $11,000 that is less than $19,000.
If we deposit $200 every month for 5 years qe would get $17,000 which is still less.
If we deposit $300 every month we would get $23,000 which is not less so the correct answer is $300.
