Best ResponseYou've already chosen the best response.0At first i said this.... First you do 3/15 x 100. This = 20. Now you have to add 20 and 100, that = 120. Maxine spent 18 hours doing homework last week. For this part you subtract 18  15. The answer will be 3. Then you divide 2 and 15 = 0.3. 0.2 x 100 = P. P= percent. 0.2 x 100 = 20. 20 + 100 = 120. Maxine as correct.

Best ResponseYou've already chosen the best response.3She spend 20% more on homework (not 120% more) You should think like this: 15 hours + 3 more hours the 3 more hours is 20% of the original in other words she worked 20% more than the first week
