[a] Write a sentence to match the equation, and expresses the relationship between the profit and the number of tickets sold.

[b] what will the profit be if 450 people attend?(Use the equation)

[c] how many tickets need to be sold to make a profit of $500?

Answer 1

P = 5T - 1000

Profit is revenue minus cost which equates to $5 times

the number of ticlets sold minus the fixed cost of $1000.

 

b). P(450) = 5(450)-1000 = 2250-1000 = $1250

 

c). 5T - 1000 = 500

     5T = 1500

     T = 1500/5

     T = 300 tickets sold to profit $500
