Q: Millie, Monica, and Marius are taking subjects for school. Millie takes three more subjects than Marius, who takes 4 subjects more than Monica. If Monica took 10 subjects, how many subjects all take altogether?
A: If Monica took ten subjects, Marius took 10 + 4 = 14 subjects. Marius and Monica have 14 + 10 = 24 subjects which they've taken. Since Millie is taking three more subjects than Marius, she is taking 14 + 3 = 17 subjects. Together, the three have taken 24 + 17 = 41 subjects. The answer is 41.
Question: Nelly wants to buy pizza for herself and her 14 friends. Each pizza costs $12 and can feed 3 people. If Nelly earns $4 a night babysitting the neighbors' kids, how many nights will she have to babysit to afford the pizza?

[Question]Hugh had eight pounds of candy, Tommy had six pounds of candy, and Melany had seven pounds of candy. If they share the candy equally, how much will each person have?
[Answer]Hugh and Tommy have a total of 8 + 6 = 14 candies. Since Melany also has seven candies, they have 14 + 7 = 21 candies. If they combine and share the candies equally, each person will get 21 / 3 = 7 candies. The answer is 7.
Q: Courtney liked to collect marbles. She kept them in mason jars. One jar had 80 marbles. Her second jar had twice that amount. She just started her third jar which currently has 1/4 the amount of her first jar. How many marbles does she have in total?
A: One jar had 80 and the second jar had twice that amount so 2 * 80 = 160 marbles. The third jar had 1 / 4 of the first jar's 80 marbles so it had .25 * 80 = 20 marbles. When you add up all the jars, she had 80 + 160 + 20 = 260 marbles. The answer is 260.
Question: Alissa used discarded paper to make notepads for her friends. She would fold 5 pieces of letter-size paper 3 times then cut along the edges to form smaller note papers. She would then stack these smaller note papers and staple them together. How long would 1 notepad last if someone wrote 10 notes per day?
Answer: Alissa folding it 3 times makes 2 × 2 × 2 = 8 pieces of note - size paper per letter - size paper. So 5 pieces of letter - size paper make 5 × 8 = 40 pieces of note - size paper. 1 note pad would last 40 ÷ 10 = 4 days if someone wrote 10 notes a day. The answer is 4.
Q: Mike is 16 years old. His sister Barbara is half as old as he is. How old is Barbara going to be when Mike is 24 years old?
