Question 144872: 4. Your profit P is determined by subtracting the cost C (the amount of money it costs to operate a business) from the revenue R (the amount of money you earn from selling your product). Profit can be represented algebraically by the equations:
Profit=Revenue-Cost
OR
P = R - C
a) Rewrite the formula to solve for C.


b) Suppose your profit for one day is $1,281, and the cost of running the business for the day is $1,463. What is the revenue for that day? Explain your answer.

part a: P=R-C. Add C to both sides, then add -P to both sides.

part b: Solve P=R-C for R using a method similar to that shown in part a. Substitute the given values for P and C, then do the arithmetic.
