Plotting the data to get the line of best fit, it is:
y<span> = 0.087</span>x<span> + 0.587
substitute x=2030-1980=50,
y = $4.94 is the price in 2030</span>
(1,115),(3,205)
slope = (205 - 115) / (3 - 1) = 90/2 = 45
the plumber charges $ 45 for each hr worked
This is probably wrong but my guess is 13 so maybe verify it but that’s my best!
P(n) = 70n - 1500....let me break this down for you
profit = revenue - expenses
so the revenue, what is made from selling tickets.....70n....where n represents the number of tickets....the 70 represents the cost of each ticket.
the 1500 is the expenses. So for them to make a profit, they would have to sell more then $ 1500 worth of tickets.
the price of a single ticket is $ 70 <==
