Answer:
a. $3,600 - $400 × m
b. $3,600 - $400 × m = $2,000
c. $3,600 is the initial account balance of the bank checking account
$400 × m is the amount removed from the account after t months such that the final account balance of the bank checking account is $2,000
$2,000 is the final account balance of the bank checking account
d. P lease find attached, the required plot and the included solution to part (b)
Step-by-step explanation:
The given information are;
The initial account balance of the bank checking account = $3600
The amount removed from the account monthly for the car payment = $400
a. The expression representing the amount in her account (her account balance) is given as follows;
Amount in her account is $3,600 - $400 × m
Where;
m = The number of months
b. The equation whose solution is the amount of months, m, it takes for the account balance to reach $2,000 is given as follows;
$3,600 - $400 × m = $2,000
c. The parts of the equation are;
$3,600 = The initial account balance of the bank checking account
$400 × m = The amount removed from the account after t months such that the final account balance of the bank checking account is $2,000
$2,000 = The final account balance of the bank checking account
d. Please find attached the required plot and the included solution to part (b)
