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

Let 14x be the number of pennies in a piggy bank

Let 3x be the number of quarters in the 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 the bank is 42
