Answer:
Monthly payments=$418.14
Total amount will be=down payment + 48×$418.14
$14000+$20070.84=$34070.84
Step-by-step explanation:
Loan payment per month=Amount to pay÷discount factor
Mathematically P=A÷D
where D is the discount factor calculated using the formula;

where i=periodic interest rate=annual rate divided by number of payment periods
A is the amount to pay after downpayment
P is the loan monthly payment amount
n=number of periodic payments=payments per year times number of years
⇒In this question you find the discount factor then divide the amount remaining to pay with the discount factor to get monthly payments
Given;
Cost of boat=$32000
Down payment=$14000
Loan to pay=$32000-$14000=$18000
Annual rate=5.5%=i=5.5%÷12=0.458%⇒0.00458
Periodic payments, n=4×12=48
Finding the discount factor D;

To get the amount to pay monthly divide the loan to pay with the discount factor

Monthly payments=$418.14
Total amount will be=down payment + 48×$418.14
$14000+$20070.84=$34070.84
