Q: Jonathan enjoys walking and running for exercise, and he has three different exercise routines. On Mondays, he walks at 2 miles per hour. On Wednesdays, he walks at 3 miles per hour. And on Fridays, he runs at 6 miles per hour. On each exercise day, he travels 6 miles. What is the combined total time, in hours, he spends exercising in a week?

[Answer]The down payment Rita made was 120 / 2 = 60 dollars. The balance was therefore 120 - 60 = 60 dollars. To pay off the balance within 10 days, Rita must make payments of 60 / 10 = 6 dollars per day. The answer is 6.
Q: Claire has 400 flowers in her garden. One hundred twenty are tulips, and the rest are roses. Eighty of the roses are white, while the rest are red. Each red rose is worth $0.75. How much will Claire earn if she can sell 1/2 of the total number of red roses?
A: Claire has 400 - 120 = 280 roses in her garden. Thus, she has 280 - 80 = 200 red roses. One - half of the red roses is equal to 1 / 2 x 200 = 100. Therefore, Claire will earn $0.75 x 100 = $75 if she can sell 1 / 2 of the total number of red roses. The answer is 75.
