Question 1178005: Al saves pennies. He agreed to give 4/9 of his pennies to Bev if she would give 4/9 of what she got from Al to Carl and if Carl in turn would give 4/9 of what he got from Bev to Dani. Bev, Carl, and Dani agreed and Dani received 448 pennies. How many pennies did Al have initially?
Answer by greenestamps(13200) (Show Source): You can put this solution on YOUR website!
Al initially had x pennies.
Bev got (4/9)x pennies from Al.
Carl got (4/9)((4/9)x) pennies from Bev.
Dani got (4/9)((4/9)((4/9)x)) pennies from Carl.
The number of pennies Dani got was 448:
(4/9)((4/9)((4/9)x)) = 448
(64/729)x = 448
x = 448*(729/64) = 7*729 = 5103
ANSWER: Al had 5103 pennies
