How do I do this??
Suppose we open up the newspaper to find that the average price or gasoline p(subscript g) is increasing by 2 cents per day, while the average price of a barrel of oil p(subscript o) is rising by $1:50 per day.
Assuming all other factors remain constant, at what rate would you say the price of gas is
increasing with respect to the price of oil? Demonstrate this as a related rate, using the fact
that we’ve assumed that p(sub g) = f(p(sub o)) for some function f.
