[Question]A school is planning a community outreach program. Each classroom must raise $200 for this activity. Classroom A has raised $20 from each of two families, $10 from each of eight families, and $5 from each of ten families. How much more money does Classroom A need in order to reach the goal?
[Answer]Classroom A raised 2 x $20 = $40 from two families. They raised 8 x $10 = $80 from eight families. They raised 10 x $5 = $50 from ten families. Altogether, they raised $40 + $80 + $50 = $170. Therefore, they need $200 - $170 = $30 more to reach the goal. The answer is 30.
Q: Janette went camping for 5 days. She brought along 40 pieces of beef jerky. She wants to ration it out so that she can eat 1 for breakfast, 1 for lunch, and 2 for dinner each day. When she returns from the trip, she plans on giving half of the remaining pieces to her brother. How many pieces of beef jerky will she have left once she does this?
A: Each day she eats a total of 1 + 1 + 2 = 4 pieces of jerky. For the entire trip, she will consume a total of 4 * 5 = 20 pieces of jerky. She gives half to her brother, which will leave her a total of 20 / 2 = 10 pieces of jerky. The answer is 10.
Question: John eats 10 potato chips that have a total of 60 calories. He then eats 6 cheezits that each have 1/3 more calories than a chip. How many total calories did he eat?
Answer: The chips each have 60 / 10 = 6 calories. That means the cheezits have 6 / 3 = 2 calories more than each chip. So they have 6 + 2 = 8 calories each. That means they have 6 * 8 = 48 total calories. So in total, he ate 60 + 48 = 108 calories. The answer is 108.
[Question]Mark has an egg farm. His farm supplies one store with 5 dozen eggs and another store with 30 eggs each day. How many eggs does he supply these two stores in a week?
[Answer]Since a dozen is equal to 12, then Mark's egg farm supplies one store with 5 x 12 = 60 eggs each day. It supplies the two stores with a total of 60 + 30 = 90 eggs each day. Therefore, the egg farm supplies the two stores with 90 x 7 = 630 eggs in a week. The answer is 630.
