    Using ounces, the inequality should be:

    15c + 70b < 112,000

    Using pounds, the inequality should be:

    0.9375c + 4.375b < 7,000

    Step-by-step explanation:

    1. Let's review the information provided to us to answer the question correctly:

    Weight of a can of soft drink (c) = 15 ounces

    Weight of a bottle of soft drink (b) = 70 ounces

    The truck mist be carrying less than 7,000 pounds

    2. Find the inequality describing this.

    Let's recall that 1 pound = 16 ounces and 1 ounce = 0.0625 pounds

    c = Number of cans in the truck

    b = Number of bottles in the truck

    Upon saying that, we can write the inequality either using ounces or pounds, this way:

    Using ounces, the inequality should be:

    15c + 70b < 7,000 * 16

    15c + 70b < 112,000

    Using pounds, the inequality should be:

    15 * 0.0625c + 70 * 0.0625b < 7,000

    0.9375c + 4.375b < 7,000
