Question: A frog lays her eggs over a series of 4 days.  The first day she lays 50 eggs.  The second day, she doubles her production of eggs.  The third day she lays 20 more than the second day, and the last day she doubles the first three days total.  How many eggs did the frog lay over the span of the 4 days? Is final answer 810?
Answer: Day 1:50
Day 2:50(2)=100
Day 3:100+20=<<100+20=120>>120
Day 4:2(50+100+120)=540
Total:50+100+120+540=<<50+100+120+540=810>>810 eggs
#### 810
