    D. 3.35

    Step-by-step explanation:

    First we need to form an equation and solve it to find the number of weeks when the prices were the same. Because the prices were the same we can say that b = c, and therefore form the equation:

    2.35 + 0.25x = 1.75 + 0.4x - Now we nee to solve it and find x.

    2.35 - 1.75 = 0.4x - 0.25x

    0.6 = 0.15x

    x = 0.6 : 0.15

    x = 4 weeks

    So now we substitute x into the equation for beef and find the price.

    b = 2.35 + (0.25 * 4)

    b = 2.35 + 1

    b = $3.35 per pound
