144.

S = 6(x^2)

For 145(a), we let x = 1000 and solve for C.

For 145(b), we let x = 2000 and solve for C.

Let B = balance at the end of the month.

B = 210 + 80 - 120 + 25 - (60 + 32) + 5

B = $108

You say?

B = 210 + 80 - 120 + 25 - (60 + 32) + 5 ..........5 is monthly service charge, should be deducted
B = 210 + 80 - 120 + 25 - (60 + 32) -5=98

Ok. Thanks. I assume the rest are correct?
