We have a question: Bethany loved riding horses. She rode 1 hour after school every Monday, Wednesday, and Friday. On Tuesday and Thursday, she rode for 30 min and on Saturdays, she could ride for 2 hours. How many hours in total did she ride over a 2 week period?
And an answer: 12
So how you got the answer?
She rode 1 hour every Monday, Wednesday and Friday each week so every week she rode 1 * 3 = 3 hours. She rode 30 min on Tuesday and Thursday each week for a total of 30 * 2 = 60 min or 1 hour. On Mon, Wed & Friday she rode 3 hours, 1 hour total on Tue and Thur and 2 hours on Sat for a total of 3 + 1 + 2 = 6 hours. She rode 6 hours per week for 2 weeks so in total she rode 6 * 2 = 12 hours.

We have a question: Pat’s computer password is made up of several kinds of alphanumeric and symbol characters for security. He uses a string of eight random lowercase letters, a string half that length of alternating upper case letters and numbers, and one symbol on each end of the password. How many characters in all is Pat‘s computer password?
And an answer: 14
So how you got the answer?
The second string of characters is half as long as the first string, so it is 8 / 2 = 4 characters long. The password has one symbol on each end, so it has 1 * 2 = 2 symbol characters. In all, Pat’s computer password is 8 + 4 + 2 = 14 characters long.

We have a question: Merill has twice as many marbles as Elliot and the two of them together have five fewer marbles than Selma. If Selma has fifty marbles, how many marbles does Merill have?
And an answer: 30
So how you got the answer?
If Selma has fifty marbles, then Merill and Elliot together have 50 - 5 = 45 marbles. We'll assume the number of marbles that Elliot has is x. If Merill has twice as many marbles as Elliot, then the total number of marbles that Merill and Elliot have together is 2x + x = 45 marbles. This translates to 3x = 45. The number of marbles that Elliot has is x = 45 / 3. This means Elliot has x = 15 marbles. Since Merill has twice as many marbles as Elliot, Merill has 2 * 15 = 30 marbles.
