It costs $6 per pound for peanuts at Blessed Food Market. Which of the following represents the range of the function in terms of cost per pound?

A. $6

B. Amount of peanuts

C. Cost of peanuts purchased

D. peanuts purchased

The range (which in fact represents the y-axis) in this case represents the cost of the peanuts purchased. If we'd make a function of your story the variable in the function would be the amount of peanuts purchased (this would therefore be the domain). Now we multiply this by the cost of one peanut, and find the total cost (which is represented on the y-axis and therefore the range).

Hence, the answer is C.
