    8 = 2^3

    I just replaced 8 with the cube of 2, so that we then have a difference of cubes. :)

    As I tell students all the time, the only dumb question is the one you don't ask. ;)

    Also I'm having some issues with these two word problems


    The gas mileage m, in miles per gallon, obtained during a long trip is given by
    m = − 1/2|s − 55| + 20
    where s is the speed of Kate's automobile in miles per hour and
    40 ≤ s ≤ 70.
    At what constant speed can Kate drive to obtain a gas mileage of exactly 13miles per gallon (Enter your answers as a comma-separated list.)

    A retailer determines the retail price of a coat by first computing 175% of the wholesale price of the coat and then adding a markup of $6.00. What is the wholesale price of a coat that has a retail price of $146.00?
