d. 2e^-2x

Question 7 - A chocolate manufacturing firm faces a demand function given by Q = 20 - 2P where Q is bars of chocolate and P price per bar, while it's cost function is given by TC = 50 + 2Q. At its current level of output of 6 bars per day, the firm is maximizing its profit, true or false?

Question 8 - Which of the following gives the derivative with respect to x for the expression y = (2x-3)/(x+1).

a. x - 3

b. 5/(x+1)²

c. 5/(x+1)

Question 9 - A brick manufacturing firm faces demand function given by P = -2Q + 60, while the production function is given by Q = L^½, where, Q id units of brick, P is price per unit and L is the total labour employed. The marginal Revenue Product of Labour (MRPL) is defined as dR/dL. What is the MRPL is this case?

a. (-4L+60)/2L^½

b. -2 + 30/L^½

c. -4L

d. (60)/(2L)

Question 10 - National income accounting states that Y = C + I + G; income = consumption plus investment plus government spending. Consumption depends upon after-tax income and hence income depends upon the tax rate t. Solving these equations for particular values of the parameters yields the equation

Y = 300/(0.2+0.8t)

Given this, what is the value of the tax multiplier, i.e. dY/dt?

a. -240/(0.2+0.8t)

b. 1/(1-0.8)

c. -300/(0.2+0.8t)²

d. -240/(0.2+0.8t)²
