A supermarket charges $1.17 for a 12-oz jar of salsa and $1.89 for a 20-oz jar. Now the producer is introducing a 16-oz jar of the same salsa. What do you think would be a fair price for this new size?

as long as the function is linear, you can use ratios to solve what the 16-oz jar would cost.  Let's see if it's linear by graphing the points.  x axis will be the number of ounces and y axis will be the cost of the jar.

I don't think the function is linear, so that's a problem.  What I did was find the average cost of one ounce of salsa.  This was .096 cents per ounce.  I multiplied that by 16 ounces and got 1.54
