The demand for good X is estimated to be Q_x^d= 91 3P_x 2P_y+ 3M+ A_x, where P_xis the price of X, P_yis the price of good Y, M is income and A_xis the amount of advertising on X. Suppose the present price of good X is $45, P_y= $30, M = $28, and A_x=60units.

1. The own price elasticity at these values is[1]. It is[2]. The total revenue will[3]if the firm increase the price of good X.

2. The cross elasticity at these values is[4]. Good X and good Y are[5].

3. Based on the information, the consumption of good X will[6]by[7]% if income drops by 3%.

4. The consumption of good X will increase by 6% if the amount of advertising on X increases by[8]%
