Question

charmaine’s penny bank is 2/3 full . after she removes 120 pennie’s , it is 1/2 full . how many pennie’s can charmaine’s bank hold ?

Answer 1

Let x be the total pennies charmaine’s bank hold

From the question, we have

`\begin{gathered} (2)/(3)x-120=(1)/(2)x \\ \\ multiply\text{ through by 6} \\ \\ 4x-720=3x \\ \\ 4x-3x=720 \\ \\ x=720 \end{gathered}`

The answer is 720 pennies
