A retail shop has determined that the number of shorts they sell on a summer day is a function of the day’s high temperature, and is approximately given by N ( H ) = 3 H − 42 N(H)=3H−42, where H H is the day’s high temperature, and 78 ≤ H ≤ 118 78≤H≤118. Suppose that the predicted high temperatures for the next 7 days are given in the table below.
