    The 2 boxes of nails will cost him $ 2.88.

    Step-by-step explanation:

    Cost of a given substance is the amount of money needed to acquire it. The total cost involved in the purchase of a given number of units is equal to the cost of one unit multiplied by the total number of units.

    Total cost = Cost of 1 unit * Total number of units ... equation 1

    Given: Boxes of nails to be bought = 8

    Price of 2 boxes of nails = ?

    Assuming the money to be in dollars ($).

    The given equation used to calculate the cost of 8 units or boxes of nails:

    11.52 = (1.44) 8 ... equation 2

    By comparing equations (1) and (2), we get

    The cost of 1 box of nails = $ 1.44

    and the total cost of 8 boxes of nails = $ 11.52

    ∴ The total cost of 2 boxes of nails = cost of 1 box of nails * 2 = $ 1.44 * 2 = $ 2.88

    Therefore, the 2 boxes of nails will cost him $ 2.88.
