The grocery store sells potatoes at a certain price per pound. If William buys five pounds of potatoes, the cost will be $2.80. If he decided that he wanted to buy twelve pounds of potatoes, how much will he spend?
Correct Answer
B. $6.72
Explanation
If William buys five pounds of potatoes for $2.80, we can find the cost per pound by dividing the total cost by the number of pounds. $2.80 / 5 = $0.56 per pound. To find the cost of twelve pounds, we multiply the cost per pound by twelve. $0.56 * 12 = $6.72. Therefore, if William buys twelve pounds of potatoes, he will spend $6.72.

The total amount he spent on shoes, jeans, and shirts can be calculated by multiplying the number of each item by its respective cost and then adding them all together: (2 * $133.44) + (3 * $50.40) + (9 * $36.54) = $1043.96. Therefore, the correct answer is $1043.96.

Tyler built twenty birdhouses to sell at the Winter Carnival. Each birdhouse cost $6.72 for materials. If he sold the birdhouses for $10.20 each and sold all twenty of them, how much money did he make after he paid for his materials?
Correct Answer
D. $69.60
Explanation
Tyler made $10.20 for each birdhouse sold and he sold twenty of them. So, the total amount of money he made from selling the birdhouses is 20 x $10.20 = $204.00. However, he spent $6.72 for materials for each birdhouse, so the total amount he spent on materials is 20 x $6.72 = $134.40. To find out how much money he made after paying for his materials, we subtract the amount spent on materials from the total amount made, which is $204.00 - $134.40 = $69.60. Therefore, Tyler made $69.60 after he paid for his materials.

Alyssa is helping her mother bake cookies for the block party. They want to bake 924 cookies! If they bake seven-dozen cookies each day, how many days will it take them to bake all the cookies? (One dozen equals 12)
Correct Answer
A. 11 days

Austin was given the job of making sure there was enough water for his family's 10 cows. The bucket Austin used only held 9 liters of water. How many times would he have to take water to the drinking trough each day if each cow drank 72 liters of water?
Correct Answer
A. 80 trips
Explanation
Austin needs to make sure there is enough water for his family's 10 cows. Each cow drinks 72 liters of water. The bucket Austin uses can only hold 9 liters of water. To calculate how many times he needs to take water to the drinking trough each day, we divide the total amount of water needed by the amount of water the bucket can hold. 10 cows x 72 liters of water = 720 liters of water. 720 liters of water / 9 liters per trip = 80 trips. Therefore, Austin would have to take water to the drinking trough 80 times each day.
