Answer:
720 pennies
Step-by-step explanation:
Initially the Penny bank is 1/2 full
After removing 120 pennies it is 1/3 full;
Therefore. the fraction equivalent to 120 pennies is;
1/2 -1/3 = 1/6
Thus; Assuming the number of pennies that the penny bank can hold when full is x; then;
1/6 of x = 120
x = 120 × 6
= 720 pennies
Hence, when the penny bank is full it can hold 720 pennies.
