Yoko's penny bank is 2/5 full. After she adds 320 pennies, it is 2/3 full. How many pennies can Yoko's bank hold?
sergejj [24]

Answer: 1200 pennies

Step-by-step explanation:

Let x be the number of pennies Yoko's bank can hold.

We can set up an equation representing the information given.

\frac{2x}{5} + 320 = \frac{2x}{3}

We can multiply both sides by 15:

6x + 4800 = 10x

Combine like terms:

4x = 4800

Divide both sides by 4:

x = 1200
