Question: James decides to go to prom with Susan. He pays for everything. The tickets cost $100 each. Dinner is $120. He leaves a 30% tip. He also charters a limo for 6 hours that cost $80 per hour. How much did it all cost?
Answer with step-by-step thinking: He paid 100 * 2 = $200 for tickets. The tip for dinner was $120 * .3 = $36. So he paid $120 + $36 = $156 for dinner. The limo cost $80 * 6 = $480. In total he paid $200 + $156 + $480 = $836.
So the answer is 836.


Question: Eva learns for two semesters in a year. In 2019, she scored ten more marks in maths in the first semester than the second, 15 marks less in arts, and 1/3 marks less in science in the first semester than the second. If she got 80 marks in maths in the second semester, 90 marks in arts, and 90 in science, what's the total number of her marks in all the semesters?
Answer with step-by-step thinking: In the first semester, she scored 80 + 10 = 90 marks in maths. She also scores 90 - 15 = 75 marks in arts in the first semester. She scored 1 / 3 marks less in science in the first semester than the second, which is 1 / 3 * 90 = 30. Her score in science in the first semester is 90 - 30 = 60. The total for the first semester is 90 + 75 + 60 = 225. The total for the second semester is 90 + 90 + 80 = 260. The combined marks for all the semesters in 260 + 225 = 485.
So the answer is 485.


Question: A clerk can process 25 forms per hour. If 2400 forms must be processed in an 8-hour day, how many clerks must you hire for that day?
Answer with step-by-step thinking:
One clerk can process 25 x 8 = 200 forms in a day. To process the forms for that day 2400 / 200 = 12 clerks must be hired.
So the answer is 12.
