Q: Mrs. Taylor bought two smart televisions that cost $650 each. If the total sales price had a 25% discount, how much did Mrs. Taylor pay for the two televisions?
A: The total cost of the two smart televisions is $650 x 2 = $1300. The total discount of the two smart televisions is $1300 x 25 / 100 = $325. Mrs. Taylor paid $1300 - $325 = $975 for the two smart televisions. The answer is 975.
Question: John drinks 2 energy drinks. 1 of them is a 12-ounce drink with 250 grams of caffeine. The second drink is 3 times more caffeinated per ounce but only 2 ounces. He then takes a caffeine pill that has as much caffeine as his 2 drinks combined. How much caffeine did he consume?
Answer: The second drink was 2 / 12 = 1 / 6 the size of the first drink. So it had 1 / 6 * 3 = 1 / 2 the caffeine. That means it had 1 / 2 * 250 = 125 grams of caffeine. So the total amount of caffeine he drank was 125 + 250 = 375 grams. So he consumed 375 * 2 = 750 grams of caffeine for the day. The answer is 750.
[Question]Troy had 300 straws. He fed 3/5 of the straws to the adult pigs and an equal number of straws to the piglets. If there were 20 piglets, how many straws did each piglet eat?
[Answer]The adult pigs ate 3 / 5 * 300 = 180 straws. The total number of straws that the piglets shared is 300 - 180 = 120. Since there were 20 piglets, each piglet ate 120 / 20 = 6 straws. The answer is 6.
Q: Derek is watching the construction cranes downtown and is trying to figure out how much taller they have to be than the building they are building. He sees one crane that is 228 feet tall finishing a building that was 200 feet tall. He sees another that is 120 feet tall finishing a building that is 100 feet tall. The final crane he sees is 147 feet tall, finishing a building that is 140 feet tall. On average, what percentage taller are the cranes than the building?
A: The first crane is 14 percent taller because if 200 + 200x = 228 then x = .14. The second crane is 20 percent taller because if 100 + 100x = 120 then x = .2. The third crane is 5 percent taller because if 140 + 140x = 147 then x = .5. The total percent is 39 because 14 + 20 + 5 = 39. The average percent greater the height of the crane is than the building is 13 because 39 / 3 = 13. The answer is 13.
Question: A young girl pours 23 blue beads and 16 yellow beads into a bowl. She divides the total into 3 equal parts, removes some beads from each part, and doubles the rest to have 6 beads in each part now. How many beads were removed from each part?
Answer: There are 23 + 16 = 39 beads in the bowl. Dividing them into 3 equal parts give 39 / 3 = 13 beads each. Before doubling the number of beads, she had 6 / 2 = 3 beads left in each part. Therefore she had removed 13 - 3 = 10 beads from each part. The answer is 10.
Q: Carmen is counting the cars that pass by her window. All the cars are either white, black, or red. She sees 50 trucks and 40 cars. Half the trucks are red, and another 20% are black. If she picks one car at random, what is the percentage chance it's a white truck, rounded to the nearest integer?
A:
First find the total number of vehicles Carmen counted: 50 trucks + 40 cars = 90 vehicles. Then find the number of trucks that were red: 50 trucks / 2 = 25 trucks. Then find the number of trucks that were black: 50 trucks * .2 = 10 trucks. Then subtract the red and black trucks from the total number of trucks to find the number of white trucks: 50 trucks - 25 trucks - 10 trucks = 15 trucks. Then divide the number of white trucks by the number of vehicles and multiply by 100% to find the percentage of vehicles that are white trucks: 15 trucks / 90 vehicles * 100% = 16.66...%, which rounds up to 17%. The answer is 17.
