Answer this question:A construction company is building 2 apartment buildings with 12 floors each. The apartments are almost ready to sell but all of them need doors to be completed. Each floor has 6 apartments, and each apartment needs 7 doors in total. How many doors does the company need to buy?
The number of floors is 12 floors / building x 2 buildings = 24 floors. The number of apartments is 6 apartments / floor x 24 floors = 144 apartments. The company has to buy 7 doors / apartment x 144 apartments = 1008 doors.
The answer is 1008.

Answer this question:A rival football team has won twice as many matches as the home team they will be playing did. If records show that the home team has won three matches, and each team drew four matches and lost none, how many matches have both teams played in total?
The rival team won twice as many as the home team who won 3 matches so they won 2 * 3 = 6 matches. They both drew 4 matches each for a total of 2 * 4 = 8 matches. The total number of matches played is 3 + 6 + 8 = 17 matches.
The answer is 17.

Answer this question:After working out for 3 hours, three friends go out for lunch. Adam spends two-thirds as much money on lunch as Rick. Rick and Jose eat lunch of the same price. If Jose ate lunch worth $45, what is the cost of lunch for all three?
Since Rick and Jose's lunch cost was the same, Adam spent 2 / 3 * 45 = $30 on his lunch. The three friends ate food worth 30 + 45 + 45 = $120.
The answer is 120.
