Caroline can sketch 8 cartoon strips in two hours. How long will it take her to sketch

12 strips?

Your answer would b 3 hours because if you realize its going up by fours and 4 times 3 is 12 so your answer is 3 hours

So start with subtracting 12 and 8 to get 4. You know it takes 2 hours to sketch 8 of the 12 which leaves the 4 left. There are half the strips so, it will take half the time. In the end, it will take them 3 hours.
