Question

A charity organization had a fundraiser where each ticket was sold for a fixed price $70. They had to sell a few tickets just to cover necessary production costs. After selling 10 tickets, they were still at a net loss of $800(due to the production costs). Let p represent the net profit (in dollars)when they have sold n tickets

Answer 1

p = 70n -1500

Explanation:

The slope-intercept form of the equation is ...

p = 70n +b

We know that p = -800 for n = 10, so we can find b:

-800 = 70·10 +b

-800 -700 = b = -1500

The net profit equation is ...

p = 70n -1500
