The following information shows a relationship between the amount spent perweek
on advertising by a small fast-food shop and the total sales per week:
Use this information to make a line graph and then predict the weekly sales associated
with the expenditure of $50 (per week) on advertising.
Amount spent 10 20 30 40
Sales 200 380 625 790
So plot your amount spent along the x-axis and your sales on the y-axis, and extend the line out to $50. Nt much else we can help you with on this one.
