Chapter 1.1, Problem 17E

To determine

**To sketch:** The graph of the amount a particular brand of coffee is sold by a store as a function of the price of the coffee.

Expert Solution

Take the price of a coffee in the *x*-axis and the amount of a particular brand of coffee sold by a store in the *y*-axis.

As the price increases, the number of items sold by the store decreases. The rough graph of the amount of the particular brand of coffee sold by the store as a function of the price of the coffee is shown below in Figure 1.

Note that the amount of a particular brand of coffee sold by the store is inversely proportional to the price of the coffee.
