Question

I'm having a hard time figuring out how to set up an equation for the following: The grocery store sells various sizes of packages of frozen chicken nuggets. FOr example, a 12-ounce package sells for $3.53, and the 18-ounce size costs $4.97. Assume that the cost ofr these items increases with a constant rate per ounce. Find the equation that relates the cost (y, in cents) and x, the number of ounces.

Answer 1

Identify the variation as direct, inverse, joint or combined.

V = r²h

Answer 2

p varies directly as q. When q = 31.2, p = 20.8. Find p when q = 15.3.

Answer 3

I was thinking that I had to use "e" since it has the constant rate and that the equation would be something like y=____e^x

Answer 4

Am I making it too hard?
