The suggested trtail price of a new car is p dollars. The dealership advertised a factory rebate of $1200
and an 8% dealership discount.
-------------------------------------
a. Write a function R in terms of p giving the cost of the car after receiving the rebate from the factory.
---
R(p) = p - 1200
============================================
b. Write a function S in terms of p giving the cost of the car after receiving the dealership discount.
---
S(p) = p - 0.08p = 0.92p
=============================================
c. Form the composite functions (R o S)(p) and (S o R)(p) and interpret each.
RoS = R[S(p)] = R[0.92p] = (0.92p)-1200
Interpretation: The 8% discount is applied 1st, then the 1200 rebate.
--------------------------------------------------
d. Find (R o S)(18,400) and (S o R)(18,400. Which yields the lower cost for the car? Explain
---
Don't recognize that notation.
