The Soft-toy company knows from past experience that if it charges P rand per
teddy bear the number sold per week will be x teddy bears, where
P = 10 − 0, 001x . The cost to produce x teddy bears per week is given by
C = 5000 + 2x rand. Select the mathematics equations for the revenue and profit
functions of the company.


a. 2
T R = 10x − 0, 001x ; π = −0, 001x
2
+ 8x − 5 000


b. 2
T R = 10 − 0, 001x ; π = 5 000 + 2x


c. T R = 10 − 0, 001x; π = −0, 001x
2
− 2x − 4 990


d. 2
T R = 10 − 0, 001x ; π = −0, 001x
2
+ 2x − 4 990




Question 4

where P is price per item and Q is the number of units produced (in thousands). The
daily fixed costs amount to R40 and the production cost per unit is R10. How many
units should be produced per day to break even?
