I need some help for a math problem. I don't know if my equation is right or not. Thanks so much for any help!(adsbygoogle = window.adsbygoogle || []).push({});

P:

Farmer Jack sells one-gallon cartons of milk (4 quarts) for $3.09 each and half-gallon cartons for $1.65 each. Assume that the number of cents you pay for a carton of milk varies linearly with the number of quarts the carton holds.

a. Write the paticular equation expressing price in terms of quarts.

b. If Farmer Jack sold 3-gallon cartons, what would your equation to predict the price be?

c. The actual prices for pint cartons (1/2 quart) and one quart cartons. Do these prices fit your mathematical model? If not, are they higher than predicted, or lower?

So, for my equation:

if P= number of cents, n=number of quarts, and k= a constant

p/n=k

How do I put that in slope intercept and standard form? Thanks again for any help!
