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.
[Question]A movie ticket costs $5. The cost of the popcorn is 80% of the cost of the ticket and a can of soda costs 50% of the cost of the popcorn. A family bought 4 tickets, 2 sets of popcorn, and 4 cans of soda. How much did they spend?
[Answer]The cost of the popcorn is $5 x 80 / 100 = $4. The cost of a can of soda is $4 x 50 / 100 = $2. The cost of 4 tickets is $5 x 4 = $20. The cost of 2 sets of popcorn is $4 x 2 = $8. The cost of 4 cans of soda is $2 x 4 = $8. Therefore, the family paid a total of $20 + $8 + $8 = $36. The answer is 36.
Q: A spider has eight legs. If a group of spiders has 10 more spiders than half as many legs as a single spider has, what is the total number of spider legs in this group of spiders?
A: Half as many legs as a single spider has is 8 / 2 = 4 legs. 10 more spiders than half as many legs as a single spider has is 4 + 10 = 14 spiders. The total number of spider legs in a group of 14 spiders is 8 * 14 = 112 spider legs. The answer is 112.
Question: It takes Jason 30 minutes to cut 1 lawn in his neighborhood. If he cuts 8 yards on both Saturday and Sunday, how many hours does he spend cutting grass?
Answer: He cuts 8 yards on both Saturday and Sunday so that's 2 * 8 = 16 yards. It takes him 30 minutes to cut 1 yard so it takes him 30 * 16 = 480 minutes. There are 60 minutes in 1 hour and it takes him 480 minutes so that's a total of 480 / 60 = 8 hours. The answer is 8.
[Question]A single kabob stick has 4 cubes of beef. A slab of beef that costs $25 can be cut into 80 cubes. How much must Simon spend to make 40 kabob sticks?
[Answer]One slab of beef can make 80 / 4 = 20 kabob sticks. To make 40 kabob sticks, Simon needs 40 / 20 = 2 slabs of beef. Simon must spend $25 x 2 = $50. The answer is 50.
[Question]John drinks 2 energy drinks. 1 of them is a 12-ounce drink with 250 grams of caffeine. The second drink is 3 times more caffeinated per ounce but only 2 ounces. He then takes a caffeine pill that has as much caffeine as his 2 drinks combined. How much caffeine did he consume?
[Answer]
The second drink was 2 / 12 = 1 / 6 the size of the first drink. So it had 1 / 6 * 3 = 1 / 2 the caffeine. That means it had 1 / 2 * 250 = 125 grams of caffeine. So the total amount of caffeine he drank was 125 + 250 = 375 grams. So he consumed 375 * 2 = 750 grams of caffeine for the day. The answer is 750.
