Compute the monthly payment and the total amount spent for a vehicle that costs $$19,400$ if you finance the entire purchase over $5$ years at an annual rate of $7\mathrm{.}50$ percent. Calculate the payment if you finance the car for only four years. Finally, calculate the payment for three years. What do you notice about the payment under the different time assumptions? Note: Round intermediate computations to at least five $(5)$ decimal places.
