[Question]A car manufacturing company that produces 100 cars per month wants to increase its production to reach 1800 cars per year. How many cars should the company add to the monthly production rate to reach that target?
[Answer]Let Y be the number of cars needed to be added to the current monthly production. Then ((100 + Y) * 12) = 1800. So 1200 + 12 * Y = 1800. 12 * Y = 1800 - 1200 = 600. Y = 600 / 12 = 50. The answer is 50.
[Question]There are 248 pages in a book. Joanna can read 16 pages per hour. On Monday, she reads for 3 hours. On Tuesday, she reads for 6.5 hours. How many more hours does she need to read to finish the book?
[Answer]
On Monday, Joanna reads 3 * 16 = 48 pages. On Tuesday, Joanna reads 6.5 * 16 = 104 pages. So far, she has read 48 + 104 = 152 pages. Thus, she has 248 - 152 = 96 pages left. She will need to read for 96 / 16 = 6 hours to finish the book. The answer is 6.
