Remember, to the find the volume, you have to do length*width*height.
So it would be 7/4 * 3/2 * 1/2
To answer this, multiply all the numerators together, and multiply all the denominator together.
This would be:
21/16
So the answer is 21/16 cm^3 or 1.3125 cm^3.

Your equation would be like this:
y=11x+300
because 11 depends on 'X" how many miles he walks and then just add 300 to that because that is the fixed amount
I hope I've helped!
