The following information shows a relationship between the amount spent perweek
on advertising by a small fastfood 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 xaxis and your sales on the yaxis, and extend the line out to $50. Nt much else we can help you with on this one.
