We have a question: Every day, Billie bakes 3 pumpkin pies for 11 days and puts them in the refrigerator. It takes 2 cans of whipped cream to cover 1 pie. If Tiffany comes over and eats 4 pies, how many cans of whipped cream does Billie need to buy to cover the remaining pies?
And an answer: 58
So how you got the answer?
In total Billie bakes 3 x 11 = 33 pies. After Tiffany eats the pies, this many pies are in the refrigerator: 33 - 4 = 29 pies. She needs to buy this many cans of whipped cream 29 x 2 = 58 cans.

We have a question: Carolyn counts 6 monkeys and 6 birds in the tree outside her window. Then two of the monkeys each eat one bird. What percent of the animals outside her window are monkeys now?
And an answer: 60
So how you got the answer?
First find the new number of birds: 6 birds - 2 birds = 4 birds. Then find the new total number of animals: 6 monkeys + 4 birds = 10 animals. Then divide the number of monkeys by the number of animals and multiply by 100% to express the answer as a percentage: 6 monkeys / 10 animals * 100% = 60%.

We have a 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?
And an answer: 810
So how you got the answer?
Day 1:50. Day 2:50(2) = 100. Day 3:100 + 20 = 120. Day 4:2(50 + 100 + 120) = 540. Total:50 + 100 + 120 + 540 = 810 eggs.
