I need help with this problem:

Esperanto Corporation wants to determine a linear function relating price, p(x), to demand where x = number of doodads sold. They sold 600 doodads per week when price was 84 dollars for each doodad. The number of doodads sold dropped to 300 doodads per week when price was raised to 93 dollars for each doodad. Write the function that models price as a function of number of doodads sold.

p(x) =

anonymous · Answer

relationship between price for each unit and total number would be p = ax + b (since this a linear relationship) . Plug in the two given conditions to find the value of a and b. 

p = (-9/300)*x + 102
