$Y = $PS * S + $PT   * T.   (* means multiplied)

Let   $Y = $500, $PS = $5, and $PT = $2.50  

1)    Graph this PPF (S on the horizontal axis and T on the vertical axis).     

2)    What is the slope of the PPF? Does it change as we move along it? Why or why not? 

3)    What is the relative price of S in terms of T? What does that phrase: "relative price of S in terms of T..." translate into in English? Please explain.

4) What is the relative price of T in terms of S?
