Answer:
The number of pennies in the bank is 42
Step-by-step explanation:
Solution:
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
