Answer the following question.
My new house has 12 medium ceiling lights but I have seen small and large ceiling lights in other rooms. The small ones require 1 bulb, the medium ones require 2, and the large ones need 3 bulbs. How many bulbs should I buy if my wife says she saw twice as many large ceiling lights as medium ceiling lights and ten more small lights than medium ones?
Step-by-step reasoning process: If the house has twice the number of large ones as medium ones then the house has 2 * 12 = 24 large ceiling lights. Similarly, if it has 10 more small ones than the 12 medium ones then it has 10 + 12 = 22 small ceiling lights. If one small ceiling light requires 1 bulb then 22 small ones will require 1 * 22 = 22 bulbs. If one medium ceiling light requires 2 bulbs then 12 medium ones will require 2 * 12 = 24 bulbs. If one large ceiling light requires 3 bulbs then 24 medium ones will require 3 * 24 = 72 bulbs. Therefore the house will require 22 bulbs for the small ones + 24 bulbs for the medium ones + 72 bulbs for the large ones, for a total of 22 + 24 + 72 = 118.
The answer is 118.

Answer the following question.
In 6 years, Carla will be 30 years old. The sum of the current ages of Carla and Louis is 55. How old is Louis now?

Answer the following question.
While bird watching, Gabrielle saw 5 robins, 4 cardinals, and 3 blue jays. Chase saw 2 robins, 3 blue jays, and 5 cardinals. How many more birds, in percentage, did Gabrielle saw than Chase?
Step-by-step reasoning process: Gabrielle saw 5 + 4 + 3 = 12 birds. Chase saw 2 + 3 + 5 = 10 birds. So, Gabrielle saw 12 - 10 = 2 more birds than Chase. Therefore, Gabrielle saw 2 / 10 x 100% = 20% more birds than Chase.
The answer is 20.

Answer the following question.
The math teacher would be happy if the class average test score was at least 85. There are 10 students in the class, 5 of which scored a 92 on the test and 4 of which scored an 80. What would the last student have to score to at least make the teacher happy?
Step-by-step reasoning process: 5 students scored a combined total of 92 * 5 = 460. 4 additional students scored a combined total of 80 * 4 = 320. 9 students therefore scored a combined total of 460 + 320 = 780. We know the total combined score for 10 students must be at least 85 average * 10 students = 850. Therefore, the last student must score at least an 850 - 780 = 70.
The answer is 70.
