Answer the following question.
Christine makes money by commission rate. She gets a 12% commission on all items she sells. This month, she sold $24000 worth of items. Sixty percent of all her earning will be allocated to her personal needs and the rest will be saved. How much did she save this month?
Step-by-step reasoning process: This month, Christine earned a commission of 12 / 100 x $24000 = $2880. She allocated 60 / 100 x $2880 = $1728 on her personal needs. Therefore, she saved $2880 - $1728 = $1152 this month.
The answer is 1152.

Answer the following question.
Vincent’s washer broke so he had to go to the laundromat. On Wednesday he washed six loads of clothes. The next day he had time to wash double the number of loads he did the day before. On Friday he had a test and could only manage half of the loads he did on Thursday. On Saturday the laundromat closed at noon and he could only wash a third of the loads of laundry he did on Wednesday. How many loads of laundry had he washed that week?
Step-by-step reasoning process: On Thursday he washed 6 * 2 = 12 loads of laundry. On Friday he washed 12 / 2 = 6 loads of laundry. On Saturday he washed 6 / 3 = 2 loads of laundry. In total he washed 6 + 12 + 6 + 2 = 26 loads of laundry.
The answer is 26.

Answer the following question.
Harry's birthday was three weeks after the closing of the school. His three friends decided to contribute an equal amount of money to throw him a party. Harry added $30 to the contribution, making the total contribution three times as much as Harry contributed. Calculate the total amount of money that each of Harry's friends contributed.
Step-by-step reasoning process: If the total contribution was three times as much as Harry contributed, and Harry contributed $30, the total contribution was 3 * $30 = $90. Since Harry contributed $30, his three friends together contributed $90 - $30 = $60. Since the three friends were contributing an equal amount, each friend contributed $60 / 3 = $20.
The answer is 20.

Answer the following question.
Whenever Katie and her family eat donuts, they need some coffee to dunk them in. She notices that for each donut they need 2 ounces of coffee. Every pot of coffee she makes contains 12 ounces and costs $3 to make. If her family finishes 3 dozen donuts, how much do they spend on coffee?
Step-by-step reasoning process: He family eats 36 donuts because 3 x 12 = 36. They need 72 ounces of coffee for these because 2 x 36 = 72. This is equal to six pots of coffee because 72 / 12 = 6. This will cost $18 to make because 6 x 3 = 18.
The answer is 18.
