For a hockey team fundraiser, Greg’s team is selling chocolate bars for $4.50 each but must pay a shipping charge of $40.00. The equation P = 4.50n – 40 can be used to represent the profit , P, the team will make after selling, n, number of chocolate bars.

 

Write the equation using function notation.

 

Find P(100).

 

What does P(100) mean?

 

Find n when P(n) = 230

 

What does P(n) = 230 mean?

P(100) will be the profit from selling 100 bars

 P(100)   =   4.5*(100) - 40    = ........

 

 

  P(n) =   230 =  4.5 (n) - 40

               270 = 4.5 n

                   n = 270 / 4.5   = .......

P(n) = 230      means after selling 'n' bars the profit is 230
