Answer:

5

Explanation:

The amount of money in the savings account can be modeled as ...

64.96 +69.80n

where n is the number of deposited checks. We want this value to be at least 400, so we must solve ...

64.96 +69.80n ≥ 400

69.80n ≥ 335.04

n ≥ 335.04/69.80

n ≥ 4.8

You must deposit 5 paychecks to reach your goal.
