document.write( "Question 1207886: A cereal company finds that the number of people who will buy one of its products in the first month that it is introduced is linearly related to the amount of money it spends on advertising.If it spends $40,000 on advertising, then 100,000 boxes of cereal will be sold,and if it spends $60,000,then 200,000 boxes will be sold. \r

document.write( "(a)Write a linear equation that relates the amount Aspent on advertising to the number x of boxes the company aims to sell.\r
\n" );
document.write( "\n" );
document.write( "I must find a linear equation in the form f(x) = mx + b. I can do this by using the points (40,000, 100,000) and (60,000, 200,000) to find the slope. After finding the slope, I think use the point-slope formula to find my linear equation.\r
