CalcAB Chp 4-4 Help with Pg 228 #27 Maximize profit Option #1: Instead of setting up the problem using x = # of people Set up a new variable; n, it is used as a counter for the number of changes made to the people and price per person. # people (#units) $ per person (price per person) n counts the # of changes 50 $200 0 (no change) 51 $198 1 52 $196 2 53 $194 3 (50+n) (200 2n) revenue = (#units) (price per person) R(n) = (50+n)(200 2n) cost = (cost per unit) (#units) + fixed amount C(n) = 32(50+n) + 6000 profit = revenue cost P(n) = (50+n)(200 2n) [32(50+n) + 6000 ] simplify P(n) = 1000 +100n 2n 2 [ 1600 + 32n + 6000 ]

Unformatted text preview: P(n) = 6600 + 68n 2n 2 maximum profit set P(n)=0 P(n) = 68 4n = n = 17 Question asks how many people will max. profit # people = 50 + 17 = 67 people Option #2: Use x = # of people price per person: 200 2(x 50) (price goes down 2 for each person more than 50) revenue: R(x) = x [ 200 2(x 50) ] simplify: R(x) = 300x 2x 2 cost: C(x) = 6000 + 32x ($6000 is fixed and each person costs $32) profit: P(x) = 300x 2x 2 [6000 + 32x] simplify: P(x) = 2x 2 + 268x 6000 derivative: P'(x) = 4x + 268 = 0 x = 67 people will maximize profit...
