1如果将价格从12美元降低到10美元,公司的收入将发生多少变化?需求在此范围内是弹性还是无弹性?| When P = $12, R = ($12)(1) = $12. When P = $10, R = ($10)(2) = $20. Thus, the price decrease results in an $8 increase in total revenue, so demand is elastic over this range of prices.

如果将价格从4美元降低到2美元,公司的收入将会发生多少变化?需求在这个范围内是弹性的还是无弹性的?| When P = $4, R = ($4)(5) = $20. When P = $2, R = ($2)(6) = $12. Thus, the price decrease results in an $8 decrease total revenue, so demand is inelastic over this range of prices.

什么价格可以使公司的总收入最大化?此时需求曲线上的需求弹性是多少?| Total revenue is maximized at the point where demand is unitary elastic. We also know that marginal revenue is zero at this point. For a linear demand curve, marginal revenue lies halfway between the demand curve and the vertical axis. In this case, marginal revenue is a line starting at a price of $14 and intersecting the quantity axis at a value of Q = 3.5. Thus, marginal revenue is 0 at 3.5 units, which corresponds to a price of $7 as shown below

网游可爱名字 假设商品X的需求自身价格弹性为-2,收入弹性为3,广告弹性为4,商品与商品Y之间的需求的交叉价格弹性为-6。确定在以下情况下其消耗量将改变多少:

一种。商品X的价格上涨了5%。
b。优质Y的价格上涨10%
C。广告减少2%
d。收入下降3%

用自己的需求价格弹性公式来写
% ΔQxy /5=2
quantity demanded of good X will decrease by 10 percent if the price of good X increases by 5 percent.

b

Use the cross-price elasticity of demand formula to write % ΔQ/10=-6 demand for X will decrease by 60 percent if the price of good Y increases by 10 percent.

C...
