They hope that 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?Suppose you work in a clothing store. Each week you earn $250 plus a commission equal to 2.5% of your sales. This week your goal is to earn no less than $350. Write and solve an inequality to find the amount of sales you must have to reach your goal.Of the 320 consumers polled, some purchased Blu-ray movies, some purchased movies on DVD, and some do both. If 300 people polled purchase Blu-ray discs and 280 purchase DVDs and Blu-ray discs, how many people only buy DVDs?The ideal length of a certain nail is 20 mm.
