Al saves pennies. He agreed to give 3/5 of his pennies to Bev if she would give 3/5 of what she got from Al to Carl and if Carl in turn would give 3/5 of what he got from Bev to Dani. Bev, Carl, and Dani agreed and Dani received 297 pennies. How many pennies did Al have initially?

A = the pennies that Al had initially

Al gives (4/9) a pennies to Bev

Bev gives (4/9) (4/9) a to Carl

Carl gives (4/9) (4/9) (4/9) a to Dani

Dani received (4/9) (4/9) (4/9) a = 960 pennies

(4/9) (4/9) (4/9) a = 960

(64/729) a = 960

a = (960*729) / 64

a = 10,935 pennies

Al had 10,935 pennies initially.
