NARA [144]

Answer:

$1615.05

Step-by-step explanation:

First, you need to determine the total cost for taking 15 credit hours:

Total cost=660+(113.67*15)

Total cost=$2,365.05

Now, you can subtract from that the amount of the grant and the scholarship you receive:

$2,365.05-$350-$400=$1615.05

According to this, the answer is that if you are taking 15 credit hours, you will need to pay $1615.05 for your classes next semester.
