A firm sells their product for R900 per item. Their fixed costs amounts to R1 500 and the variable cost is R300 per unit produced. Calculate the value of the total revenue (TR) and total cost (TC) at break-even.
a. TR 2 250; TC = 2 250.
b. TR = 2 700; TC = 2 400.
c. TR = 900; TC = 900.
d. TR = 2700; TC = 2 700.
