The cost C(in dollars) for the care and maintenance of a horse and carriage is C=15x+2000. the company charges $35 per ride. Write an equation for the revenue R in terms of the number of rides
so let R equal to the revenue of the company x be the number of rides since the cost per ride is $ 35 so the equation for revenue is R = 35x the profit can also be solve profit = revenue - cost
profit = R - C profit = 35x - 15x - 2000 profit = 20x - 2000
