Question: About 450 000 people lived in Maryville in 2000. In 2005, about 467 000 people lived in Maryville. What is the average number of people added each year?

[Answer]Twice the number of pigs is 10 x 2 = 20. So, Hannah's family has 20 - 3 = 17 cows. They also have 17 + 6 = 23 goats. So, they have a total of 10 + 17 + 23 = 50 animals on their farm. The answer is 50.
Q: To raise money, a school is selling ice-pops for $1.50. It costs 90 cents to make each pop, and the money from the pops will be used to buy pencils, which cost $1.80 each. How many pops must be sold to buy 100 pencils?
A: To buy 100 pencils the school needs 100 * $1.80 = $180.00. Each ice pop sells for $1.50 but costs $.90 to make, for a net profit of $1.50 - $.90 = $.60. So in order to raise $180.00, the school will need to sell $180.00 / $.60 per ice - pop = 300 ice - pops. The answer is 300.
