Consider the Q and A. Q: Donna made a cake to take to a party where the guests ate half the cake. The day after the party, she shared half the leftovers with her brothers. The following day, she ate one piece as a midnight snack. Twice as many pieces as her snack were left. How many pieces was the cake to begin with?
A: 12
What is the step-by-step reasoning process?
Step-by-step reasoning process: Donna had 2 * 1 = 2 pieces of cake left. Before her snack, there were 2 + 1 = 3 pieces left. Those 3 pieces were half the leftovers, so she had 3 * 2 = 6 pieces before sharing with her brothers. Those 6 pieces were half the party leftovers, so the cake was 2 * 6 = 12 pieces before the party.

Consider the Q and A. Q: Tim drinks 2 bottles that are each 1.5 quarts and an additional 20 ounces a day. How much water does he drink a week?
A: 812
What is the step-by-step reasoning process?
Step-by-step reasoning process: The bottles are 1.5 * 32 = 48 ounces. So he drinks 48 * 2 = 96 ounces from the bottles. So in total he drank 96 + 20 = 116 ounces a day. 116 * 7 = 812 ounces a week.

Consider the Q and A. Q: 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?
A: 14
What is the step-by-step reasoning process?
Step-by-step reasoning process: 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.

Consider the Q and A. Q: Princeton had a gender reveal party and invited all of his fellow employees to celebrate with him. If the total number of guests were 60, and 2/3 were male guests, how many female guests attended the party?
A: 20
What is the step-by-step reasoning process?
Step-by-step reasoning process:
The number of males in the party was 2 males / 3 guests * 60 guests = 40 males. If the total number of people at the party was 60, then there were 60 guests - 40 males = 20 females.
