PL A local car dealership is trying to sell all of the cars that are on the lot. Currently, there are 525 cars on the lot, and the general manager estimates that they will consistently sell 50 cars per week. Estimate how many weeks it will take for the number of cars on the lot to be fewer than 75.

A. Write an inequality that can be used to find the number of full weeks, w, it will take for the number of cars to be fewer than 75. Since w is the number of full or complete weeks, w=1 means at the end of week 1.

b. Solve and graph the inequality

inequalities taking care to interpret the solutions in the context of the problem.
