Question:

1. Los chicos ______ alegres. A. son B. están 2. La chica _______ cansada. A. es B. está 3. Los pollos _______ blancas. A. son B. Están

Jacob T.

The answer to #1 is B because alegre (which means happy) is a condition, it is not permanent so that is why the correct answer is están. How you feel or where you are always use the verb estar!! The answer to #2 is B because cansada is the way that the girl is feeling at the moment and it doesn't mean that she is tired all the time. This is why we use the verb estar. How you feel or where you are always use the verb estar! The answer to #3 is A. "Blancas" describes the chickens and is a permanent characteristic that the chickens have and that is why we use the verb ser.

Question:

Timmy and his 3 friends all order a pizza while they watch the hockey game. They order from Belly Up Pizza and they ordered a large pizza and they cut the pizza in 12 slices. Tim ended up eating 7 slices of pizza. What is the ratio of how many slices Timmy ate compared to the whole pizza? And what is the percentage of pizza that Timmy's friends ate?

Jacob T.

We first look at the important information and we see the two most important pieces of information are that there are 12 slices of pizza and that Timmy ate 7 slices of pizza. We know that the whole pizza contains 12 slices of pizza. In order to find the ratio of how many slices Timmy ate we divide the number of slices Timmy ate by the total number of slices in the pizza. The answer is 7/12 for the number of pizza slices Timmy ate compared to the whole pizza. The next part of the question then asks the percentage of pizza that Timmy's friends ate. First we have to figure out how many slices Timmy's friends ate. We know that Timmy ate 7 slices which means the rest of the pizza was eaten by Timmy's friends. So we subtract 12-7 and that equals 5. It is another ratio setup so we use the 5 (which is the number of slices Timmy's friends ate) and divide it by 12 (which is the whole number of slices) 5/12 = .4166. Since we are looking for a percentage we have to multiply .4166 x 100 which equals 41.66%. Which means that Timmy's friends ate 41.66% of the pizza.

Question:

Terry goes to the local clothing store in search for a new jacket. She is looking for the cheapest jacket but also one that she likes. She finds jacket A which is \$125 but is also on sale for 30% off or jacket B which is \$115 and is also on sale but is 25% off. Which jacket is the cheapest for Terry to buy?

Jacob T.

Terry should buy jacket B because it is cheaper than jacket A. When looking at jacket A, you set up the problem \$125 x .30 because that shows what 30 percent of \$125 equals. \$125 x .30 = \$37.50. Now we use \$37.50 and subtract it from \$125 because that shows what 30% off would equal which equals \$87.50. Now we do the same set up for jacket B which is \$115 x .25 which equals \$28.75. We use \$28.75 and subtract it from \$115 which is \$86.25. Now comparing both jackets you see that Jacket B is the cheaper option and is the one that Terry should buy!
