There are 2000 pinecones on the ground. 20% are eaten by reindeer. Twice as many are eaten by squirrels as reindeer. 25% of the remainder are collected to make fires. How many pinecones are left? Give the rationale and then the answer.
Let's think step by step. First find the number of pinecones eaten by reindeer: 20% * 2000 pinecones = 400 pine cones. Then find the total number of pinecones eaten by squirrels: 400 pine cones * 2 = 800 pine cones. Then subtract those two amounts to find the number of pinecones left: 2000 pinecones - 400 pine cones - 800 pine cones = 800 pinecones. Divide that number by 4 to find the number that are collected for fires: 800 pinecones / 4 = 200 pine cones. Then subtract that number from the 800 pinecones to find the total left on the ground: 800 pine cones - 200 pinecones = 600 pine cones.. The answer is: 600.

The average GPA for 6th graders is 93, the 7th graders is 2 more than the 6th graders and the 8th graders average GPA is 91. What is the average GPA for the school? Give the rationale and then the answer.
Let's think step by step. The 7th graders average GPA is 2 more than the 6th graders GPA of 93 so 93 + 2 = 95. If you combine the GPA for all three grades then they have 93 + 95 + 91 = 279. The average GPA for the school is 279 / 3 = 93.. The answer is: 93.

Shaniqua styles hair. For every haircut she makes $12 and for every style she makes $25. How many dollars would Shaniqua make if she gave 8 haircuts and 5 styles? Give the rationale and then the answer.
Let's think step by step. Haircuts = 8 * 12 = 96. Styles = 5 * 25 = 125. Total earned = 96 + 125 = $221.. The answer is: 221.
