Question 14
A ski resort has three pricing options: 60 dollars for just a lift ticket, 20 dollars for just a ski lesson, or 70 dollars when both are bought together. On Sunday, 50 people bought exactly one of the three options. If 42 lift tickets and 23 lessons were sold, what was the mean purchase amount, in dollars, for these 50 people? Round your answer to the nearest whole number.
In the illustration, 42, 23 and 50 are numbers of people; 60, 70 and 20 are prices in dollars, not numbers of people.
