2 Answer

  • Answer:

    6 pounds.

    Step-by-step explanation:

    70-25.36= 44.64 (the amount of money she spent)

    44.64/7.44 (per pound cost)= 6

  • Answer:

    Rachel bought 6 pounds of coffee.

    Step-by-step explanation:

    First, do $70-$25.36, because that will give you the total amount of money she spent on coffee.

    $70-$25.36= $44.64.

    Rachel spent $44.64 on coffee.

    Next, you know that every pound of coffee costs $7.44.

    So, $7.44x = $44.64

    x= the number of pounds of coffee Rachel purchased.

    So, we have to now isolate x.

    $7.44x / $7.44 = $44.64 / $7.44

    x= 6

    Therefore, Rachel purchased 6 pounds of coffee.
