A: A 40% discount on each kilogram of apples would mean the price being 40 / 100 * 5 = $2 smaller. So one kilogram of apples would cost not $5, but 5 - 2 = $3. So for 10 kilograms of apples Hannah would pay 3 * 10 = $30. The answer is 30.
Question: Jose had 400 tabs opened up in his windows browser. After about one hour of browsing, he closed 1/4 of the tabs to allows easy browsing. He read some news from different pages, then closed 2/5 of the remaining tabs. If he closed half of the remaining tabs after further analyzing some pages, how many windows tabs did he have remaining open?
Answer: When he closed 1 / 4 of the tabs, he closed 1 / 4 * 400 = 100 tabs. The number of windows tabs that remained open is 400 - 100 = 300. After reading some news from different pages, he closed 2 / 5 of the remaining tabs, a total of 2 / 5 * 300 = 120 pages. The number of tabs that remained open is 300 - 120 = 180. If he closed half of the remaining tabs after further analyzing some pages, he closed a total of 1 / 2 * 180 = 90 pages. The total number of tabs that remained opened is 180 - 90 = 90. The answer is 90.
