Given:-
Estimated cost per semester
Tuition fee(T) =$10000

Room and board(R)=$10030
Other expense(O)=$1570
Now,
1] To find the estimated cost to attend this college for 1 semester.
Answer:-
Estimated cost for 1 semester(E)= Tuition fee+Books+Room and Board+Other expense
[tex]E=T+B+R+O[/tex]
[tex]E=10000+1200+10030+1570[/tex]
[tex]Estimated\ cost\ for\ 1\ semester=22800[/tex]
Therefore estimated cost to attend this college for 1 semester = $22800
2]Each year has 2 semester. How many semester will Joe pay for if he attends for 4 years.
Answer:-
If 1 year has 2 semester, then
total semester in 4 years=[tex]2\times 4[/tex]
total semester in 4 years=8
Therefore Joe will pay for 8 semester if attends for 4 years.
3] What is the estimated total cost for Joe to attend this college for 4 years.
Estimated total cost for 4 years = Estimated total cost for 1 semester[tex]\times[/tex]8
Estimated total cost for 4 years=22800[tex]\times[/tex]8
Estimated total cost for 4 years =$182400
