Step-by-step reasoning process: Ginger has 2 children whom she bakes for 4 times a year, for 2 * 4 = 8 cakes. She makes her husband 6 cakes a year. She makes each of her 2 parents a cake for 2 * 1 = 2 cakes. On a yearly basis, she therefore makes 8 + 6 + 2 = 16 cakes. In 10 years, she would make 16 * 10 = 160 cakes.
[Q & A] The question is Ginger likes to make cakes for every holiday for people. She has 2 children, each of whom she bakes a cake for on their birthdays, Christmas, Easter, and Halloween. She has a husband for whom she makes a cake on these same holidays, as well as on their anniversary and Valentine's Day. Lastly, she makes both her parents cakes as well, but only for their birthdays since they live far away. How many cakes does she make in 10 years?
The answer is 160

Step-by-step reasoning process: The total number of strawberries in the three baskets is 3 * 900 = 2700. If 2 / 9 of the strawberries were remaining out of all the strawberries after the hedgehogs ate some, there were 2 / 9 * 2700 = 600 strawberries remaining. The total number of strawberries that the two hedgehogs ate is 2700 - 600 = 2100 strawberries. If the hedgehogs ate an equal number of strawberries, each ate 2100 / 2 = 1050 strawberries.
[Q & A] The question is Two hedgehogs found three baskets, each with 900 strawberries. The hedgehogs then each ate an equal number of strawberries. If 2/9 of the strawberries were remaining out of all the strawberries that were there, calculate the total number of strawberries that each hedgehog ate.
The answer is 1050

Step-by-step reasoning process: If Ariella has $200 more in her son's saving account than Daniella has, then she has $400 + $200 = $600. If she earns an interest of 10% in the first year, her savings account increases by 10 / 100 * $600 = $60. In the second year, she earns the same amount of interest, which $60 + $60 = $120. The total amount of money in Ariella's account after two years is $600 + $120 = $720.
