- The demand function for specialty steel products is given, where p is in dollars and q is the number of units. p = 135V110 - g (a) Find the elasticity of demand as a function of the quantity demanded, q. (b) Find the point at which the demand is of unitary elasticity. q = Find intervals in which the demand is inelastic and in which it is elastic. (Enter your answers using interval notation.) inelastic elastic (c) Use information about elasticity in part (b) to decide where the revenue is increasing, and where it is decreasing. (Enter your answers using interval notation.) increasing decreasing Use information about elasticity in part (b) to decide where the revenue is maximized. q =arrow_forwarddemand of a product: q(p)= 10000 -1000ln(1+10)p please help in solving 1. how to compute the elasticity of demand when the price is $575 and 2. the decrease in demand in a % with 5 decimal places if the price goes up by 15%arrow_forwardB and Carrow_forward
- The demand for Widgets (QX) is a function of the price of widgets (PX), the price of woozles (PY), and per capita income (1): QX = 1950 - 10 PX + 5 PY-0.11 Currently, PX = 25, PY = 10, and 1 = 15,000. (a) Calculate the elasticity of demand for widgets with respect to its own I price, the price of woozles, and income. (b) Over what range of prices is the demand for widgets elastic? (c) If the cost per widget is 10 and the manufacturer behaves as a monopolist, how many widgets will be sold and at what price: (d) By how much must the price of widgets change if there is a 1% decrease in per capita income and the goal is to keep QX constant.arrow_forwardIf the price elasticity of a product is -.75 and the demand increases 21% over the year prior, what % change would this have on the price of the product as well as the revenue going to those who produce the product?arrow_forwardPlease answer D and Earrow_forward
