Answer:
$42,600
Step-by-step explanation:
The computation of the cost of going to college is given below:
the total cost when he goes to college he spends
21,000 on tuition
11,000 on room and board
1,800 on books
So, the total should be $33,800
Now in the case when he does not go to college
So,
he will earn 16,000 working in a store
and spend 7,200 on room and board
So, the saving amount should be
= 16,000 - 7,200
= $8,800
Now the cost should be
= 33,800+8,800
= $42,600
