You are a budding entrepreneur and begin a typing service. you buy a personal computer for $1750 on which to do your typing. you charge $5.50 per page for typing. expenses are $.50 per page for ink, paper, electricity, and other expenses. how many pages must you type to break even? a. you must type 318 pages to break even. b. you must type 636 pages to break even. c. you must type 350 pages to break even. d. you must type 292 pages to break even.

X = number of pages typed
Cost = C(x) = 0.50x+1750
Revenue = R(x) = 5.50x
Profit = P(x) = R(x) - C(x)
Profit = P(x) = 5.50x - (0.50x+1750)
Profit = P(x) = 5.50x - 0.50x - 1750
Profit = P(x) = 5x - 1750

The break even point is where the profit is 0. So we need to solve P(x) = 0 for x

P(x) = 0
5x - 1750 = 0
5x - 1750+1750 = 0+1750
5x = 1750
5x/5 = 1750/5
x = 350

The break even point is at 350 pages. This means that if you produce and sell 350 pages, then the profit is $0

The answer is choice C

The slope of the function is 0.5.
