expression 49.94x + 27.77y + 25.82z describes the cost of producing each of the handheld vacuum cleaners. Write a polynomial in simplest
Profit = revenue - cost = 56.69X + ??y + 66.74z - (49.94x + 27.77y + 25.82z) = (56.69X - 49.94X) + (??Y - 27.77Y) + (66.74z - 25.82z) = 6.75X + ((??Y - 27.77Y) + 40.92 you did not give us the revenue for the 'y' units.
