Question

Martina's penny bank is 1/6 full. After she adds 440 pennies, it is 2/3 full. How many pennies can Martina's bank hold?

Answer 1

Martina's penny bank can hold a maximum of 880 coins.

Explanation:

Initially the penny bank is
`(1)/(6)` full of coins.

Let the penny bank can hold a maximum of x coins.

After she adds 440 pennies, it is 2/3 full. This means 440 coins are added to make the bank from 1/6 to 2/3 full.

We can write this as an equation.

`(2x)/(3) -(x)/(6)` = 440

`(x)/(2)` = 440

x = 880 coins

Martina's penny bank can hold a maximum of 880 coins.
