Final answer:
To estimate the amount Carly needs to deposit into her savings account per month over the next 3 years, subtract her current savings from the anticipated cost of college and divide by the number of months.
Step-by-step explanation:
To determine the amount Carly needs to deposit into her savings account per month over the next 3 years, we can subtract her current savings from the anticipated cost of college. The calculation would be:
Amount needed to deposit per month = (Total cost of college - Carly's current savings) / Number of months
Substituting the given values, we get:
Amount needed to deposit per month = ($12,000 - $2,900) / 36
Amount needed to deposit per month = $283.33 (rounded to the nearest cent)
Therefore, a reasonable estimate of the amount Carly needs to deposit into the savings account per month over the next 3 years is $283.33.
