After trick-or-treating, Brent dumped his candy on the table. He had received 5 Kit-Kat bars, three times that amount in Hershey kisses, 8 boxes of Nerds, and 11 lollipops. He also had 10 Baby Ruths and half that amount in Reese Peanut butter cups. After giving his little sister 5 lollipops, how many pieces of candy did Brent have left? Give the rationale and then the answer.
Let's think step by step. He had 5 Kit - Kats and had 3 times that amount in Kisses so he had 5 * 3 = 15 Hershey kisses. He had 10 Baby Ruths and half that amount in Reese Peanut butter cups so he had 10 / 2 = 5 Reese Peanut Butter cups. He had 11 lollipops and gave 5 to his sister so he now had 11 - 5 = 6 lollipops. When you add up all of the candy, he had 5 Kit - Kats, 15 Hershey kisses, 10 Baby Ruths, 5 Reese cups, 8 Nerds and 6 lollipops so 5 + 15 + 10 + 5 + 8 + 6 = 49 pieces of candy.. The answer is: 49.

A company is hosting a seminar. So far, 30 attendees from company A have been registered; company B has twice the number of attendees of company A; company C has 10 more attendees than company A; company D has 5 fewer attendees than company C. If a total of 185 attendees have registered, how many attendees who registered are not from either company A, B, C or D? Give the rationale and then the answer.
Let's think step by step. There are 30 x 2 = 60 attendees from company B. Company C has 30 + 10 = 40 attendees. Company D has 40 - 5 = 35 registered attendees. So, the total attendees from company A, B, C, and D is 30 + 60 + 40 + 35 = 165. Therefore there are 185 - 165 = 20 attendees that are not from companies A, B, C, or D.. The answer is: 20.

Tom swims for 2 hours at a speed of 2 miles per hour. He then runs for half the time at 4 times the speed. How many miles did he cover? Give the rationale and then the answer.
Let's think step by step. He swam 2 * 2 = 4 miles. He ran for 2 / 2 = 1 hour. His running speed was 2 * 4 = 8 mph. So he ran 8 * 1 = 8 miles. So his total distance was 8 + 4 = 12 miles.. The answer is: 12.
