Answer :
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.
[tex]\frac{2x}{5} + 320 = \frac{2x}{3}[/tex]
We can multiply both sides by 15:
6x + 4800 = 10x
Combine like terms:
4x = 4800
Divide both sides by 4:
x = 1200
