Answer:
2744 pennies.
Step-by-step explanation:
Let x represent the number of pennies Al have initially.
We have been given that Al agreed to give 3/7 of his pennies to Bev, so number of pennies Bev will get would be .
We are also told that Bev gave 3/7 of what she got from Al to Carl, so number of pennies that Carl will get would be .
Further, Carl gave 3/7 of what he got from Bev to Dani, so number of pennies that Dani will get would be .
We are also told that Dani received 216 pennies. Now, we will equate 216 to and solve for x as shown below:
Therefore, Al have 2744 pennies initially.
