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?
+37146 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
