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

Solution

Let x be the total pennies charmaine’s bank hold

From the question, we have

$\begin{gathered} \frac{2}{3}x-120=\frac{1}{2}x \\ \\ multiply\text{ through by 6} \\ \\ 4x-720=3x \\ \\ 4x-3x=720 \\ \\ x=720 \end{gathered}$

The answer is 720 pennies
