30. Suppose you are working for a trucking company. Your job is to load a truck
with at least 5000 lb of freight. You have loaded 2395 lb of freight, but you have
to unload 50 lb that was loaded by mistake. Write and solve an inequality to
find how many more pounds you need to load.
31. The art club is sponsoring four art shows. They hope the average attendance for the four shows will be between 100 and 120, inclusive. The attendance for the first three shows was 100, 105, and 91. What possible attendance numbers for the fourth show will allow them to reach their goal? Write and solve an inequality for this situation.
