Please ignore my work!! I need help on problem a!!

3. The price p (in dollars) and the demand x for a particular steam iron are related by the equation x =1000 - 2p . - 10 ( -000 a) Express the price p in terms of the demand x, and find the domain of this function. Dom X = 1000 - 2p -7 - 2p = X- 1000 SUSP = X- 100 - 1000 - 1000 - 2 22 2 p ( x ) - X - 10 b) Find a function that computes the Revenue from the sale of x steam irons. 2 r ( x) = X ( X - 1000 * 2 - 100 0 X R ( x ) = XL - Z 2 c) Find the number of steam irons that maximizes revenue. 1000
