I get this whole problem all the way up to the part where you have to find the purchasing power is 40 cents. To do this i'm suppose to get it by, graph y=(t) and y=.40 find where they intersect. It says to round to the nearest who number. How do they even intersect? I see them as being parallel.?? Help please!!!
