Answer: c = 1.25p
----
You're told that peppers cost $1.25 per pound. That means for each pound of pepper, you would have to add another $1.25 in order to find the total cost.
Another way of saying that is by multiplying $1.25 by the number of pounds, which is represented by p. That means cost, c, equals 1.25p. Or c = 1.25p.
