    Answer:

    270 coins

    n + p

    Step-by-step explanation:

    Given that :

    Number of nickels = 140

    Number of pennies = 130

    The total numbers coins had:

    Number of Nickel + number of pennies

    140 + 130 = 270 coins

    If Number of nickels = n ; number of pennies = p

    The total number of coins :

    Number of Nickel + number of pennies

    n + p
