We have a question: Nadia was sent to the flower shop to buy 20 roses and 3/4 times as many Lillies as roses. If roses cost $5 each and lilies cost twice as much each, calculate the total amount of money Nadia used to buy the flowers.
And an answer: 250
So how you got the answer?
The total cost for roses is 20 * 5 = $100. Nadia bought 3 / 4 * 20 = 15 lilies. Each lily costs 5 * 2 = $10. She used 10 * 15 = $150 in total to buy lilies. To buy all the flowers, Nadia used 150 + 100 = $250.

We have a question: Jefferson hires a carriage to go to the church. It is 20 miles away. The horse can go 10 miles per hour. It cost $30 per hour plus a flat fee of $20. How much did he pay for the carriage?
And an answer: 80
So how you got the answer?
He paid for 20 / 10 = 2 hours. That means the hourly fee was 30 * 2 = $60. So the total cost was 60 + 20 = $80.

We have a question: John works a job that offers performance bonuses. He makes $80 a day and works for 8 hours. He has the option of working hard to earn the performance bonus of an extra $20 a day, but the extra effort results in a 2-hour longer workday. How much does John make per hour if he decides to earn the bonus?
And an answer: 10
So how you got the answer?

First, we need to determine the length of John's workday if he decides to earn the bonus. We do this by performing 8 + 2 = 10 hours for his workday. Next, we need to determine his overall pay. We do this by performing 80 + 20 = 100 dollars a day. We then determine John's hourly rate by dividing his pay by the number of hours worked, performing 100 / 10 = 10 dollars an hour.
