Answer:
(1) 0.08x + 16
(2) 0.08x + 16=0.12x + 14
Step-by-step explanation:
Checking account A has a monthly fee of $16 and a per-check fee of $0.08
Per check fee is a constant rate that is 0.08
Let x represents the number of checks Cecily writes per month
1 check fee = 0.08
x checks fee = 0.08x
monthly fee is $16 , we add that as well
So total monthly fee charges for account A is
0.08x + 16
checking account B has monthly fee of $14 and a per-check fee of $0.12.
1 check fee = 0.12
x checks fee = 0.12x
monthly fee is $14 , we add that as well
So total monthly fee charges for account B is
0.12x + 14
(2) To find number of checks write per month for the accounts to charge the same in fees
WE set both expression , account A = account B
0.08x + 16=0.12x + 14
Subtract 0.12x on both sides
-0.04x + 16 = 14
Now subtract 16 on both sides
-0.04x = -2
Divide by -0.04 on both sides
So x= 50
