[Question]A plumber is trying to decide which of three different jobs he should take to make the most money. The first job involves fixing three toilets and three sinks at an apartment complex. The second involves two toilets and five sinks at a different apartment complex. The third involves fixing one toilet, two showers and three sinks at a third apartment complex. If the plumber charges $30 to fix a sink, $40 to fix a shower and $50 to fix a toilet, what is the most money the plumber can earn if he can only choose one of these three jobs?
[Answer]If the plumber chooses the first job, he would earn 3 * 50 + 3 * 30 = $240. If he chooses the second, he'd earn 2 * 50 + 5 * 30 = $250. If he chooses the third, he'd earn 50 + 2 * 40 + 3 * 30 = $220. Therefore, the most money he can earn from one of these jobs is $250. The answer is 250.
Q: Makenna is selling candy for her Softball Team. The box contains 25 milk chocolate bars, 25 dark chocolate bars, 25 milk chocolate with almond bars, and 25 white chocolate bars. What is the percentage of each type of chocolate bar?
A: Since there are four types of chocolate bars and each type has 25 bars, the total number of chocolate bars is 25 * 4 = 100. Since there is a total of 100 chocolate bars and four types of chocolate, we divide 100 / 4 = 25%. The answer is 25.
Question: Samuel swept the porch and cleared nine-tenths of the dust particles from it. As he walked across the porch afterward, his shoes left 223 dust particles behind. How many dust particles were on the porch before Samuel swept if there were 331 after he walked across it?
Answer: Before Samuel walked across the porch, there were 331 - 223 = 108 dust particles. Those 108 were 1 / 10 of the original amount, so there were 108 * 10 = 1080 dust particles on the porch before Samuel swept. The answer is 1080.

A: The amount paid to the teacher per day is 5 periods * $5 / period = $25 per day. The amount paid for 24 days is $25 / day * 24 days = $600. The total amount for 6 months is $600 * 6 = $3600. The answer is 3600.
Question: A store has an 8% discount on all items. If Shara paid $184 for a pair of shoes, how much did Shara save?
Answer:
The price that Shara paid is only 100% - 8% = 92% of the original price. So, every 1% is equal to $184 / 92 = $2. Therefore, Shara saved $2 x 8 = $16. The answer is 16.
