A car dealership offers a $1800 rebate and a 14% discount off the price of a new car. Let p be the sticker price of a new car on the dealer's lot, r the price after the rebate, and d the discounted price. Then r(p) = p − 1800 and d(p) = 0.86p. (a) Write a composite function for the dealer taking the rebate first and then the discount. d[r(p)] = (b) Write a composite function for the dealer taking the discount first and then the rebate. r[d(p)] = (c) Which composite function would you prefer the dealer to use when you buy a new car? The dealer takes the discount first and then the rebate.The dealer takes the rebate first and then the discount.

Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
