Consider the Q and A. Q: Five percent of the 300 senior students got a full merit college scholarship and ten percent of them got a half merit scholarship. How many senior students did not get any scholarships?
A: 255
What is the step-by-step reasoning process?
Step-by-step reasoning process: 300 x 5 / 100 = 15 senior students got a full merit scholarship. 300 x 10 / 100 = 30 senior students got a half merit scholarship. So, a total of 15 + 30 = 45 students got scholarships. Therefore, 300 - 45 = 255 senior students did not get any scholarships.

Consider the Q and A. Q: Hannah has three dogs. The first dog eats 1.5 cups of dog food a day. The second dog eats twice as much while the third dog eats 2.5 cups more than the second dog. How many cups of dog food should Hannah prepare in a day for her three dogs?
A: 10
What is the step-by-step reasoning process?
Step-by-step reasoning process: The second dog eats 1.5 x 2 = 3 cups of dog food. The third dog eats 3 + 2.5 = 5.5 cups. So, Hannah should prepare 1.5 + 3 + 5.5 = 10 cups.
