Answer the following question.
It takes Jennifer 20 minutes to groom each of her 2 long hair dachshunds. If she grooms her dogs every day, how many hours does she spend grooming her dogs in 30 days?
Step-by-step reasoning process: She has 2 dogs and it takes 20 minutes to groom just 1 dog so it takes her 2 * 20 = 40 minutes per day to groom 2 dogs. In 30 days, she will have spent 30 * 40 = 1,200 minutes grooming her dogs. There are 60 minutes in an hour so she spends 1200 / 60 = 20 hours grooming her dogs.
The answer is 20.

Answer the following question.
Debelyn, Christel, and Andrena collect dolls. Debelyn had 20 dolls before she gave Andrena 2 dolls. Christel had 24 dolls before giving Andrena 5 dolls. After all the gifts, Andrena now has 2 more dolls than Christel, how many more dolls does andrena have now than Debelyn?
Step-by-step reasoning process: Debelyn had 20 - 2 = 18 dolls left after giving out 2 dolls to Christel. Christel had 24 + 2 = 26 dolls after receiving 2 dolls from Debelyn. Christel had 24 - 5 = 19 dolls after giving Andrena 5 dolls. So, Andrena has 19 + 2 = 21 dolls now. Therefore, Andrena has 21 - 18 = 3 more dolls than Debelyn.
The answer is 3.

Answer the following question.
The student council sells scented erasers in the morning before school starts to help raise money for school dances. The local bookstore donated 48 boxes of erasers. There are 24 erasers in each box. If the student council sells the erasers for $0.75 each, how much money will they make?
Step-by-step reasoning process: There are 48 boxes x 24 erasers = 1,152 erasers. The student council will make 1,152 erasers x $0.75 = $864.
The answer is 864.
