[Question]: Bob bought 2 show dogs for $250.00 each to breed as a side business. The female just had a litter of 6 puppies. If he sells each puppy for $350.00, what is his total profit?
[Answer]: He bought 2 dogs for $250.00 each so they costs 2 * 250 = $500.00. He sells each of the 6 puppies for $350.00 so he'll make 6 * 350 = $2,100.00. He made $2,100 on the puppies but spent $500.00 to buy the dogs so his total profit is 2,100 - 500 = $1,600.00.
So the answer is 1600.

[Question]: Milly is figuring out how long she needs to spend studying. She knows that her math homework will take 60 minutes. Her geography homework will take half as long as her math homework, and her science homework will take time equal to the mean amount of time she spent studying math and geography. How many minutes does Milly spend studying?
[Answer]: First find how long Milly spends studying geography by dividing her math homework time by 2: 60 minutes / 2 = 30 minutes. Now find the total amount of time Milly spent on math and geography: 30 minutes + 60 minutes = 90 minutes. Now calculate the mean amount of time Milly spends on math and geography by dividing the total time spent by the number of subjects, which is 2: 90 minutes / 2 = 45 minutes. Now add the time Milly spent on all three subjects to find the total: 45 minutes + 30 minutes + 60 minutes = 135 minutes.
So the answer is 135.

[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.
[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.
So the answer is 250.
