Question: Greg has his own dog walking business. He charges $20 per dog plus $1 per minute per dog for walking the dog. If he walks one dog for 10 minutes, two dogs for 7 minutes and three dogs for 9 minutes, how much money, in dollars, does he earn?
Answer: Single dog is $20 + (10 minutes * $1 per minute) = $30. Two dogs are 2 * ($20 + (7 minutes * $1 per minute)) = $54. Three dogs are 3 * ($20 + (9 minutes * $1 per minute)) = $87. The total is $30 + $54 + $87 = $171. The answer is 171.

Question: Sarah's external drive showed 2.4 gigabytes free and 12.6 gigabytes used. She decided to delete a folder of size 4.6 gigabytes and store new files of 2 gigabytes. If she will transfer all her files to a new external drive of size 20 gigabytes, how many free gigabytes will the new external drive have?
Answer:
There were 12.6 - 4.6 = 8 gigabytes used after deleting some files. Then, the used space went up to 8 + 2 = 10 gigabytes after storing other files. Thus, the new 20 gigabytes external drive will have 20 - 10 = 10 gigabytes free. The answer is 10.
