Q: At Sarah's job 60% of the employees are women and the rest are men. Of the men, 75% have a college degree and 8 do not. How many women work at Sarah's company?
A: 25% of men at the job don't have a college degree because 100 - 75 = 25. There are 32 men at the company because 8 / .25 = 32. 40% of the employees are men because 100 - 60 = 40. The company has 80 workers because 32 / .4 = 80. There are 48 women at the company because 80 - 32 = 48. The answer is 48.

Q: A couple agreed to split their expenses equally, including the salary of their house help. While doing her job, the house help had an accident; thus, she underwent a medical procedure which cost her $128. The couple decided to pay half of the medical expenses and the other half will be deducted from her $160 salary. If the husband paid for the entire half of the hospital bill, how much does he still need to pay so that they split the expenses for the house help equally?
A: The amount that the couple would cover for the hospital bill is $128 / 2 = $64. The couple's total expenses (salary and hospital bill) is $160 + $64 = $224. So each of them should give $224 / 2 = $112 in total. Since the husband paid the entire half of the hospital bill already ($64), he still needs to pay $112 - $64 = $48. The answer is 48.

Q: Of the 90 people on William's bus, 3/5 were Dutch. Of the 1/2 of the Dutch who were also American, 1/3 got window seats. What's the number of Dutch Americans who sat at the windows?
A:
On the bus, the number of Dutch people was 3 / 5 of the total number, a total of 3 / 5 * 90 = 54 people. Out of the 54 people who were Dutch, 1 / 2 were Dutch Americans, a total of 1 / 2 * 54 = 27 people. If 1 / 3 of the passengers on the bus identifying as Dutch Americans sat at the windows, their number is 1 / 3 * 27 = 9. The answer is 9.
