Betty has a checking account and a non-interest bearing savings account. The function C(x), shown below, represents her checking

account balance, where x is the number of months. The function S(x), shown below, represents her saving account balance.

C(x) = -2401 - 140 + 1,400

S(s) = 4503 + 100

Which function represents Betty's total account balance. T(x)?

T(x) or total account balance = C(x) + S(x)

Step-by-step explanation:

where = C(x) = -2401 - 140 + 1,400  

and

S(x) = 4503 + 100

This implies that:

C(x) = 3,661

S(x) = 4,603

Therefore, T(x) 3,661 + 4,603 = 8,264

T(x) is the total account balance or the addition of the balances of checking and saving accounts.

C(x) is the checking account balance.

S(x) is the saving account balance.
