Question: Mica went to the grocery store and bought 2 kilograms of pasta that costs $1.5; 1/4 kilogram of ground beef costs $8 for 1 kilogram; two jars of pasta sauce costs $2 per jar. Mica also wants to buy a $6 Quesadilla for snacks. How much money should she have with her to buy all those?
Answer: Two kilograms of pasta cost $1.5 x 2 = $3. One - fourth kilogram of ground beef cost $8 x 1 / 4 = $2. Two jars of pasta sauce cost $2 x 2 = $4. The total cost for the pasta, beef, and sauce is $3 + $2 + $4 = $9. Since Mica also wants to buy Quesadilla, she should have $9 + $6 = $15. The answer is 15.
[Question]Isabella has three times as many green houses as yellow houses. She also has 40 fewer yellow houses than red houses. If she has 90 green houses, how many of her houses are not yellow?
[Answer]If the number of green houses is three times the number of yellow houses, and there are 90 green houses, then there are 90 / 3 = 30 yellow houses. She also has 40 fewer yellow houses than blue houses, meaning there are 30 + 40 = 70 blue houses. The number of houses that are not yellow is 70 blue houses + 90 green houses = 160. The answer is 160.
Q: Several birds were sitting in the branches of a crape myrtle tree. There were three times more cardinals than bluebirds, but half as many swallows as bluebirds. If there were 2 swallows, what is the total number of birds in the crape myrtle tree?
A: With half as many swallows as bluebirds, there are 2 * 2 = 4 bluebirds. With three times more cardinals than bluebirds, there are 3 * 4 = 12 cardinals,. If there were 2 swallows, then the total number of birds in the crape myrtle tree is 2 + 4 + 12 = 18 birds. The answer is 18.
Question: A park warden has issued 24 citations over the past three hours. He issued the same number for littering as he did for off-leash dogs, and he issued double the number of other citations for parking fines. How many littering citations did the warden issue?
Answer: Let L be the number of littering citations the warden issued. He issued 2L citations for littering and off - leash dogs, and 2 * 2L = 4L citations for parking fines. In all, he issued 2L + 4L = 6L = 24 citations. Thus, he issued L = 24 / 6 = 4 citations for littering. The answer is 4.
