Answer the following question.
Millie, Monica, and Marius are taking subjects for school. Millie takes three more subjects than Marius, who takes 4 subjects more than Monica. If Monica took 10 subjects, how many subjects all take altogether?
Step-by-step reasoning process: If Monica took ten subjects, Marius took 10 + 4 = 14 subjects. Marius and Monica have 14 + 10 = 24 subjects which they've taken. Since Millie is taking three more subjects than Marius, she is taking 14 + 3 = 17 subjects. Together, the three have taken 24 + 17 = 41 subjects.
The answer is 41.

Answer the following question.
The town of Belize has 400 homes. One fourth of the town's homes are white. One fifth of the non-white homes have a fireplace. How many of the non-white homes do not have a fireplace?
Step-by-step reasoning process: There are 400 / 4 = 100 white homes in Belize. There are 400 - 100 = 300 non - white homes in Belize. There are 300 / 5 = 60 non - white homes that have a fireplace. There are 300 - 60 = 240 non - white homes that do not have a fireplace.
The answer is 240.

Answer the following question.
About 450 000 people lived in Maryville in 2000. In 2005, about 467 000 people lived in Maryville. What is the average number of people added each year?
Step-by-step reasoning process: The total increase of people was counted in 2005 - 2000 = 5 years. In 5 years, there is a total of 467 000 - 450 000 = 17 000 people increase. So, each year, the average number of people added is 17 000 / 5 = 3 400.

Joseph had 16 baseball cards. He gave 3/8 of the cards to his brother and 2 cards to his brother. What percentage of the cards is left to Joseph?

The answer is 50.
