Question: Janet uses her horses' manure as fertilizer. One horse produces 5 gallons of fertilizer per day. Once Janet has collected enough fertilizer, she'll spread it over 20 acres of farmland. Each acre needs 400 gallons of fertilizer and Janet can spread fertilizer over 4 acres per day. If Janet has 80 horses, how long will it take until all her fields are fertilized?
Answer: First find the total amount of fertilizer the horses produce per day: 5 gallons / horse * 80 horses = 400 gallons. Then multiply the number of acres of farmland by the number of gallons per acre to find the total amount of fertilizer needed: 400 gallons / acre * 20 acres = 8000 gallons. Then divide the total amount of fertilizer needed by the amount of fertilizer produced per day to find the number of days needed to collect fertilizer: 8000 gallons / 400 gallons / day = 20 days. Then divide the total number of acres Janet needs to cover by the number of acres she can cover per day to find how many days it takes her to cover them all: 20 acres / 4 acres / day = 5 days. Then add the time to collect the fertilizer to the time to spread it to find the total time: 5 days + 20 days = 25 days. The answer is 25.
[Question]Krystiana owns an apartment building. The rooms on the first floor cost $15 per month and the rooms on the 2nd floor cost $20 per month. The rooms on the third floor cost twice as much as the rooms on the first floor, but only two rooms are occupied. If each floor has 3 rooms, how much does Krystiana earn every month?
[Answer]Krystiana earns $15 x 3 = $45 for the rooms on the first floor every month. She earns $20 x 3 = $60 for the rooms on the second floor every month. And the cost for each room on the third floor is $15 x 2 = $30. So, the total amount she earns for the rooms on the third floor is $30 x 2 = $60 every month. Therefore, the total amount she earns from the apartment building is $60 + $60 + $45 = $165. The answer is 165.
[Question]Mr Fletcher hired 2 men to dig a well in his compound. They worked for 10 hours on the first day, 8 hours on the second day and finished the job on the third day after working 15 hours. If Mr Fletcher paid each of them $10 per hour of work, calculate the total amount of money they received altogether?
[Answer]
The total number of hours each worker works in the first 2 days is 10 + 8 = 18 hours. Since they completed the job in three days, each was compensated for 18 + 15 = 33 hours of work. Mr Fletcher paid each of the workers $10 per hour of work, meaning for 33 hours, each of the workers received 33 * $10 = $330. Since they were two workers, the total amount they received all together after each was paid $330 is $330 * 2 = $660. The answer is 660.
