Please help me with this question.. this is my 2nd time posting it and I would really appreciate it. If you could help me. Also this is calculus grade 12

Inv i t A I An electronics retailing chain has established the monthly price (p) demand (in) relationship for an electronic game as _ 4/3 mm = 1000 -(10 (\"p.123 ) They are trying to set a price level that will provide maximum revenue . They know that when demand is elastic, a drop in price will result in higher overall revenues and that when demand is inelastic, an increase in price will result in higher overall revenues. To complete the questions in this task, you will have to use the elasticity denition. E = -[(An) + (Mn/0)] converted into differential notation. (( An/ Ap) = dn/dp) a. determine the elasticity of demand at $20 and $80, classifying these price points as having elastic or inelastic demand. What does this say about where the optimum price is in terms of generating the maximum revenue? Explain. Also calculate the revenue at the $20 and $80 price points. K/U b. approximate the demand curve as a linear inction (tangent) at a price point of $50. Plot the demand function and its linear approximation on the graphing calculator or graphing software. What do you notice? Explain this by looking at the demand function. COMM 0. use your linear approximation to determine the price point that will generate the maximum revenue. (hint: think about the specic value of E, where you will not want to increase or decrease the price to generate higher revenues.) What revenue is generated at this price point? T/l
