Answer this question:A deep-sea monster rises from the waters once every hundred years to feast on a ship and sate its hunger. Over three hundred years, it has consumed 847 people. Ships have been built larger over time, so each new ship has twice as many people as the last ship. How many people were on the ship the monster ate in the first hundred years?
Let S be the number of people on the first hundred years’ ship. The second hundred years’ ship had twice as many as the first, so it had 2S people. The third hundred years’ ship had twice as many as the second, so it had 2 * 2S = 4S people. All the ships had S + 2S + 4S = 7S = 847 people. Thus, the ship that the monster ate in the first hundred years had S = 847 / 7 = 121 people on it.
The answer is 121.

Answer this question:Ever since she was a little girl, Sheila has dreamed of traveling the world. To help fund her dream, she bought a large piggy bank in December and started saving. By last week, she had saved $3,000. Pleased with her progress, she has decided to continue saving $276 per month, for 4 years. Today, Sheila’s family secretly added $7,000 into the piggy bank. At the end of 4 years, how much money will be in Sheila’s piggy bank?
Today, Sheila’s piggy bank has $3000 + $7000 = $10000. Sheila will be saving for 4 years which is equivalent to 12 months / year * 4 years = 48 months. In 4 years, she will save $276 / month * 48 months = $13248. The piggy bank will have a total of $10,000 + $13,248 = $23248.
The answer is 23248.

Answer this question:Josh built his little brother a rectangular sandbox. The perimeter of the sandbox is 30 feet and the length is twice the width. What is the width of the sandbox?
There are four sides to a rectangle, the width is W and so the length is 2W, and we can put that in this equation: W + W + 2W + 2W = 30 feet. If we add the sides together, we get 6W = 30 feet. To find W, we divide both sides by 6, like this: 6W / 6 = 30 feet / 6, so W = 5 feet.
The answer is 5.

Answer this question:A bond paper ream has 500 sheets and costs $27. An office needs 5000 sheets of bond paper. How much will it cost to buy their needed sheets of paper?
