Question 1077176: A tiny food restaurant invests $4000 to create a new food that sells for $. Each item can be produced for $. Which system shows the cost and revenue functions for items produced and sold?
C = ; R = 2.15x
C = ; R = 3.5x
C = ; R = 3.5x - 4000x
C = ; R = 3.5x

The fixed cost is $4000. Add on 2.15x dollars for the x items sold (since each item costs the restaurant $2.15 to make). In total, the cost equation would be C = 2.15x + 4000

They turn around and sell the item for $3.50. So if x of them are sold, then they take in 3.50x dollars. That's why the revenue function is R = 3.5x

The final answer is choice B) C = 2.15x + 4000 ; R = 3.5x
