(a)

To determine

The interpretation of function f(94.5,25,7)=$667.91. The monthly payment R on a loan is a function of the amount borrowed, A, in thousands of dollars; the length of the loan, n, in years; and the annual interest rate, r, as a percent. Thus, R=f(A,n,r).

(b)

To determine

The interpretation of function ∂f∂r(94.5,25,7)=$60.28. The monthly payment R on a loan is a function of the amount borrowed, A, in thousands of dollars; the length of the loan, n, in years; and the annual interest rate, r, as a percent. Thus, R=f(A,n,r).

(c)

To determine

Whether ∂f∂n(94.5,25,7) will be positive, negative or zero. The monthly payment R on a loan is a function of the amount borrowed, A, in thousands of dollars; the length of the loan, n, in years; and the annual interest rate, r, as a percent. Thus, R=f(A,n,r).
