Problema Solution
Al saves pennies. He agreed to give five elevenths
of his pennies to Bev if she would give five elevenths
of what she got from Al to Carl and if Carl in turn would give five elevenths
of what he got from Bev to Dani. Bev, Carl, and Dani agreed and Dani received 1375
pennies. How many pennies did Al have initially?
Answer provided by our tutors
Let 'x' represent the number of pennies that Al had initially.
Al gave to Bev: (5/11)x
Bev gave to Carl: (5/11)(5/11)x
Carl gave to Dani: (5/11)(5/11)(5/11)x
Dani received 1375 means:
(5/11)(5/11)(5/11)x = 1375
