**Home Mortgage** The term *t* (in years) of a $200,000 home mortgage at 7.5% interest can be approximated by

*x* is the monthly payment in dollars.

(a) Use a graphing utility to graph the model.

(b) Use the model to approximate the term of a home mortgage for which the monthly payment is $1398.43. What is the total amount paid?

(c) Use the model to approximate the term of a home mortgage for which the monthly payment is $1611.19. What is the total amount paid?

(d) Find the instantaneous rate of change of *t* with respect to x when x = $1398.43 and x = $1611.19.

(e) Write a short paragraph describing the benefit of the higher monthly payment.
