[Question]On a 16 GB (gigabyte) capacity USB drive, 50% is already busy. Calculate the number of gigabytes still available.
[Answer]We calculate 50% of 16 GB:. 50 / 100 * 16 GB = 0.5 * 16 GB = 8 GB. That leaves 16 GB - 8 GB = 8 GB available on this key. The answer is 8.
Q: Mary bought 5 boxes of drinks at $6 each box and 10 boxes of pizzas at $14 each box for her pizza party. She paid $200 for all the items. How much change did she get back?
A: Mary spent 5 x $6 = $30 on drinks. She spent 10 x $14 = $140 on pizzas. She spent a total amount of $30 + $140 = $170. Therefore, Mary got a change of $200 - $170 = $30 after paying all the items for her pizza party. The answer is 30.
Question: Shawna's workout goal is 30 situps. On Monday, Shawna was only able to do 12 situps, so she decided that she would make up for the rest on Tuesday. However, she was only able to do 19 situps on Tuesday. How many situps would Shawna have to do on Wednesday to meet her minimum goal and make up for the ones she didn't do?
Answer: On Monday, Shawna was short of 30 - 12 = 18 situps. On Tuesday, Shawna was short of 30 - 19 = 11 situps. On Wednesday, Shawna would have to do 30 + 18 + 11 = 59 situps. The answer is 59.
[Question]At football tryouts, the coach wanted to see who could throw the ball the farthest. Parker threw the ball 16 yards. Grant threw the ball 25 percent farther than Parker and Kyle threw the ball 2 times farther than Grant. Compared to Parker, how much farther did Kyle throw the ball?
[Answer]Grant threw the ball 25% farther than Parker. If Parker threw the ball 16 yards, then Grant threw it 16 * .25 = 4 farther. In total, Grant threw the ball 16 + 4 = 20 yards. Kyle threw 2 times farther than Grant so Kyle threw the ball 2 * 20 = 40 yards. If Kyle threw the ball for 40 yards and Parker threw for 16 then Kyle threw the ball 40 - 16 = 24 yards farther. The answer is 24.
Q: Cupcakes are sold in packages of 10 and 15. Jean bought 4 packs of 15 cupcakes. If she will give one cupcake each to 100 children in the orphanage, how many packs of 10 cupcakes should she need to buy?
A: Jean already bought 15 cupcakes x 4 packs = 60 cupcakes. She needs 100 - 60 = 40 more cupcakes. Thus, she needs to buy 40 / 10 = 4 packs of 10 cupcakes. The answer is 4.
Question: Tommy goes for a run around his neighborhood and decides to calculate how many wheels he saw. All the trucks in his neighborhood have 4 wheels and all the cars in his neighborhood also have 4 wheels. If he saw 12 trucks and 13 cars, how many wheels did he see?
Answer:
He saw 25 total vehicles because 12 plus 13 equals 25. He saw 100 wheels because 25 times 4 equals 100. The answer is 100.
