An electronics manufacturer can produce and sell x mp3 players per week. the total cost c (in dollars) of producing mp3 players is c = 93c + 35,000, and the total revenue r (in dollars) is r = 135x. 1. find the profit p in terms of x. 2 find the profit obtained by selling 5000 mp3 players per week.

1. The profit P in terms of x is 135x - 93x - 35,000

2. The profit is 175,000.

1. The profit P should be

p(x) =  135x - 93x - 35,000

2. Now the profit should be

P(5,000) = 135x - 93x - 35,000

= 42x - 35,000

= 42(5000) - 35000

= 210,000 - 35,000

= 175,000

Profit, or the surplus money after your costs are covered, is Revenue - Costs.

so in this case the profit P(x) = R(x) - C(x).
