8. The 2003 Zagat Restaurant Survey provides food, decor, and service ratings for some of the top restaurants across the United
States. For 15 top-ranking restaurants located in Boston, the average price of a dinner, including one drink and tip, was $48.60. You are leaving for a business trip to Boston and will cat dinner at three of these restaurants. Your company will reimburse you for a maximum of $50 per dinner. Business associates familiar with these restaurants have told you that the meal cost at one-third of these restaurants will exceed $50. Suppose that you randomly select three of these restaurants for dinner. a) What is the probability that none of the meals will exceed the cost covered by your company
So the equation looks like this : 15*3x=78 subtract 15 from both sides: -15 -15 then divide by 3 from both sides to isolate the variable: 3x=63 3/3x=63/3 x=21 (your mystery number is 21)
