[Question]Uncle Bradley has a $1000 bill that he wants to change into smaller bills so he could give them to his nieces and nephews. He wants to change 3/10 of the money into $50 bills while the rest into $100 bills. How many pieces of bills will Uncle Bradley have in all?
[Answer]There will be $1000 x 3 / 10 = $300 worth of money that will be changed into $50 bills. Uncle Bradley will have $300 / $50 = 6 pieces of $50 bills. He will change $1000 - $300 = $700 worth of money into $100 bills. So there will be $700 / $100 = 7 pieces of $100 bills. Thus, there will be a total of 6 + 7 = 13 pieces of $50 and $100 bills in all. The answer is 13.
Q: 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?
A: 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.
