Question: Mr. Maximilian has a rental building that he collects rent from every month. The number of units in the building is 100. If the building is 3/4 occupied for a whole year, and each resident of the building pays a rent of $400, calculate the amount of money Mr. Maximilian receives in that year.
Answer with step-by-step thinking: Since there are 100 units, the number of units occupied by tenants is 3 / 4 * 100 = 75. If each tenant pays $400 every month, Mr Maximilian receives 75 * $400 = $30000 in rent revenue every month. In a year, Mr Maximilian receives $30000 * 12 = $360000 in rent revenue.
So the answer is 360000.


Question: Camp Cedar has 40 boys, it has 3 times as many girls. It needs 1 counselor for every 8 children. How many counselors does Camp Cedar need?
Answer with step-by-step thinking: Camp has 3 * 40 boys = 120 girls. Camp Cedar has a total of 40 boys + 120 girls = 160 children. Camp needs 1 counselor per 8 children, so 160 children / 8 children = 20 counselors needed.
So the answer is 20.


Question: Hannah has three brothers. Her brothers are all 8 years old. How old is Hannah if she is twice as old as the sum of her brother's ages?
Answer with step-by-step thinking:
The total of Hannah's brothers' ages is 3 * 8 = 24. Hannah is twice as old as the total of her brothers' ages, so Hannah is 24 * 2 = 48 years old.
So the answer is 48.
