Answer this question:Brittany has 3 gerbils: Puffy, Muffy, and Scruffy. Puffy weighs 5 ounces more than Muffy. Muffy weighs 3 ounces less than Scruffy. If Scruffy weighs 12 ounces, how much would the scale indicate, in ounces, if Brittany put Puffy and Muffy on the scale?
Muffy weighs 12 - 3 = 9 ounces. Puffy weighs 5 + 9 = 14 ounces. If Brittany weighs both Puffy and Muffy, the scale would read 9 + 14 = 23 ounces.
The answer is 23.

Answer this question:The school decided to have a fundraiser to collect $750 for new basketball equipment. Families could donate $25, $50, or $100. Families who donated $25 got Bronze Status. Families who donated $50 got Silver Status. Families who donated $100 got Gold Status. With one day left in the fundraiser, the school has 10 Bronze Status families, 7 Silver Status Families and 1 Gold Status family. How much do they need to raise on the final day to reach their goal?
They collected $250 from Bronze Status families because 10 times 25 equals 250. They collected $350 from Silver Status families because 7 times 50 equals 350. They collected $100 from Gold Status families because 1 times 100 equals 100. Therefore, they collected $700 thus far because 250 plus 350 plus 100 equals 700. They need to collect $50 more because 750 minus 700 equals 50.
The answer is 50.

Answer this question:Keanu was surfing towards the shore at a speed of 20 miles per hour. A shark was swimming alongside him, riding the same wave, when it doubled its speed and moved away from Keanu. There was a pilot fish swimming alongside Keanu and the shark, and when the shark increased its speed, the pilot fish also increased its speed and moved away from Keanu, but only increasing its speed by half as much as the shark had increased its speed by. What speed, in miles per hour, was the pilot fish swimming when it moved away from Keanu?
The shark went from 20 miles per hour to a speed of 2 * 20 = 40 miles per hour. The shark increased its speed by 40 - 20 = 20 miles per hour. Half of the shark's increase in speed is 20 / 2 = 10 miles per hour. Thus the pilot fish had increased its speed to 20 + 10 = 30 miles per hour.
The answer is 30.

Answer this question:While preparing balloons for Eva's birthday party, her mom bought 50 balloons and 1800cm³ of helium. One balloon needs 50cm³ to float high enough to touch the ceiling, and she can fill any remaining balloon with ordinary air. If she used up all of the helium and inflated every balloon, how many more balloons are touching the ceiling than not?
50cm³ will make one balloon touch the ceiling so 1800cm³ will make 1800 / 50 = 36 balloons touch the ceiling. There are 50 balloons in total so 50 - 36 = 14 balloons will not float since they were filled with ordinary air. There are 36 - 14 = 22 more balloons touching the ceiling than not.
The answer is 22.
