Answer this question:A group of researchers are studying a colony of penguins. Their results show that the size doubled in the first year they watched the colony, then tripled in the next year. This year, however, harsh conditions meant the colony only gained 129 penguins. The colony has 1077 penguins in it now. Each penguin eats one and a half fish every day. How many fish did the whole colony catch per day to eat at the beginning of the first year?
The colony had 1077 - 129 = 948 penguins in it at the beginning of this year. At the beginning of the second year, the colony had 948 / 3 = 316 penguins in it. At the beginning of the first year, it had 316 / 2 = 158 penguins in it. Thus, at the beginning of the first year, the penguin colony was catching 158 * 1 1 / 2 = 237 fish per day.
The answer is 237.

Answer this question:Rebecca bought 22 items for her camping trip, including tent stakes, packets of drink mix, and bottles of water. She bought 3 times as many packets of drink mix as tent stakes. She also bought 2 more bottles of water than she did tent stakes. How many tent stakes did she buy?
Let x represent the number of tent stakes. Drink Mix: 3x. Bottles of Water: x + 2. Total: x + 3x + x + 2 = 22. 5x + 2 = 22. 5x = 20. x = 4 tent stakes.
The answer is 4.

Answer this question:Kyle goes to basketball practice every day for 2 hours. At practice he spends half of the time shooting and the rest of the time running and weight lifting. If he runs for twice the time he spends weightlifting, how much time in minutes does he spend lifting weight?
Half of the 2 - hour practice is for running and weightlifting, so the time for running and weight lifting is 1 / 2 * 2 hours = 1 hour. If the time he lifts weights is x, then the time he runs is 2x. So the time for running and weight lifting is x + 2x = 3x = 1 hour. Thus 3x = 60 minutes. Thus x = 60 / 3 = 20 minutes spent weight lifting.
The answer is 20.

Answer this question:Darla needs to pay $4/watt of electricity for 300 watts of electricity, plus a $150 late fee. How much does she pay in total?
First find the total cost of the electricity: $4 / watt * 300 watts = $1200. Then add the late fee: $1200 + $150 = $1350.
The answer is 1350.
