Question

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?

Answer 1

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.

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

4x = 4800

Divide both sides by 4:

x = 1200
