    The number of pennies in bank is 42

    Solution:

    Given that ratio of pennies to quarters in a piggy bank is 14 : 3

    Let 14x be the number of pennies in piggy bank

    Let 3x be the number of quarters in piggy bank

    To find: number of pennies

    Given that there are 51 quarters

    number of pennies in piggy bank + number of quarters in piggy bank = 51

    14x + 3x = 51

    17x = 51

    x = 3

    number of pennies = 14x = 14 (3) = 42

    Thus the number of pennies in bank is 42
