a ski resort has 3 pricing options on his 20 $ for a ski lesson, or 60 $ for a lift pass, or 70 $ for both lift and lesson. 50 people bought exactly one of the options, and if 42 lift tickets were sold and 23 lessons, what is the mean/average amount they paid in dollars and cents am giving all my points need answer now

$81

Step-by-step explanation:

We have:

20x (20 dollars per ski lesson)

60y (60 dollars per lift pass)

70z (70 dollars for ski lesson and pass)

We are given:

42 lift tickets sold

23 lessons sold

50 people bought 1 option

We need to find how many people bought both the ski lesson and pass:

42 + 23 = 65 things sold total

Only 50 people bought 1 item

65 - 50 = 15 people bought both ski lesson and pass

Now we find the total costs of everything combined:

70(15) + 60(34) + 60(16) = 4050

Mean: 4050/50 people = $81

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)
