Giselle predicts that she will receive a grant for $4,000. If she has 4 years in which to save, what is the minimum monthly amount she should deposit in an interest bearing savings account to be able to pay her contribution for one year of college?
$400
$500
$600

Answer 1

Total cost = 12,450 + 10,125 + 2,600 + 2,250 + 1,250 = $28,675.
After a $4,000 grant she must save $28,675 − $4,000 = $24,675.
Over 4 years (48 months) she needs 24,675 ÷ 48 ≈ $514.06 per month.

So the minimum choice that covers it is $600.
