Please ignore my work!!! I need help on question b!!

3. The price p (in dollars) and the demand x for a particular steam iron are related by the equation x =1000 - 2p . - 10 6 7000 a) Express the price p in terms of the demand x, and find the domain of this function. Domain : 05 X = 1000 - 2p - 2 p = X - 1000 SIP = X- 100 0 - 1000 - 1000 2 22 2 Z p ( x ) - X- 1000 b) Find a function that computes the Revenue from the sale of x steam irons. 2 r ( x) = X ( X - 1000 * 2 - 1600 X R ( x ) = x5- 1000 * Z 2 c) Find the number of steam irons that maximizes revenue. - 1000 - b soo 2 29 1
