How can you use a rate to compare the costs of two boxes of cereal that are different sizes?

Mathematics

If you are given a unit rate (ex: $0.59 per ounce) then you can multiple this by the weight of the cereal to find the cost of the entire box. Do this for both boxes, and then compare the costs.

Hope this helps. I'm not sure that I'm on the right path, but I can help you further if you provide more details.

Good luck!

Hello, could you please explain this to me?
Viefleur [7K]

Find the value of r(q(4)), so first you need to find the value of q(4).

q(4), this means that x = 4, so substitute/plug it into the equation to find the value of q(x) when x = 4:

q(x) = -2x - 1      Plug in 4 into "x" since x = 4

q(4) = -2(4) - 1

q(4) = -8 - 1

q(4) = -9        

Now that you know the value of q(4), you can find the value of r(x) when x = q(4)

r(x) = 2x² + 1

r(q(4)) = 2(q(4))² + 1      Plug in -9 into "q(4)" since q(4) = -9

r(q(4)) = 2(-9)² + 1

r(q(4)) = 2(81) + 1

r(q(4)) = 163           163 is the value of r(q(4))
