Answer this 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?
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.

Answer this question:Two-fifths of the seats in an auditorium that holds 500 people are currently taken. It was found that 1/10 of the seats are broken. How many seats are still available?
500 / 2 / 5 = 200 seats are already taken. 500 / 1 / 10 = 50 seats are broken. So 200 + 50 = 250 seats are either taken or broken. Therefore, 500 - 250 = 250 seats are still available.
The answer is 250.

Answer this question:The world record for longest fingernails is 26 inches. Sandy, who just turned 12 this month, has a goal for tying the record. Her fingernails are 2 inches long. Her fingernails grow at a rate of one-tenth of an inch per month. How old will she be when she achieves the world record?
Sandy's fingernails will grow a total of ( 0.1 ) * 12 = 1.2 inches per year. To achieve the world record, Sandy needs to grow her fingernails a total of 26 - 2 = 24 inches. It will take her a total of 24 / 1.2 = 20 years. Sandy will be 12 + 20 = 32 years old when she achieves the world record.
The answer is 32.

Answer this question:During the outbreak of the coronavirus, a company had to ramp up its toilet paper production three times more to cover the increased demand. If the company was producing 7000 toilet paper per day, calculate its total toilet paper production during March of 2020 after increasing its production.
If the company was producing 7000 toilet paper per day, when it ramped up its toilet paper production three times per day, it produced 3 * 7000 = 21000 more per day. The total toilet production by the company increased to 7000 + 21000 = 28000. In March, with 31 days, the company produced a total of 28000 * 31 = 868000 toilet papers.
The answer is 868000.
