Question: Blake needs to prime and paint 5 rooms in his house. Each room will require a gallon of primer and a gallon of paint. Currently the primer is $30.00 a gallon and they are offering 20% off. The paint costs $25.00 a gallon and is not on sale. How much will he spend on paint and primer?
Answer: The primer is $30.00 with 20% off so that's 30 * .20 = $6.00 off. The primer is $30.00 and the discount is for $6.00 off so the sale price is 30 - 6 = $24.00 per gallon. Blake needs 5 gallons of primer that is $24.00 a gallon so that's 5 * 24 = $120.00. He needs 5 gallons of paint that cost $25.00 a gallon so that's 5 * 25 = $125.00. The primer is $120.00 and the paint is $125.00 so all total, he will spend 120 + 125 = $245.00 on paint and primer. The answer is 245.
[Question]John and Yasmin's dad is named Gabriel. If John has twice the number of children that her sister has and Gabriel has six grandkids, how many children does Yasmin have?
[Answer]We don't know Yasmin's number of children yet, but let's represent it as Y. If John has twice the number of children Yasmin has, then John has 2 * Y = 2Y kids. If Gabriel has 6 grandkids between John's and Yasmin's children, then we can represent this as 6 = 2Y + Y. If we solve the latest equation then we learn that 6 = 3Y. Given that Y represents how many kids Yasmin has, then solving for Y we know that Y = 6 / 3 or Y = 2 kids. The answer is 2.
Q: Carl is having a party on Saturday and is inviting 15 guests. He would like to make sure everyone, including himself, has at least 2 glasses of punch. Each glass holds 12 ounces of punch. How many ounces of punch does he need to buy for the party?
A: Including Carl, there will be 15 + 1 = 16 people at the party. Carl would like each person to be able to have 2 cups x 12 ounces = 24 ounces of punch. Carl needs to buy 16 x 24 = 384 ounces of punch. The answer is 384.
Question: Sara builds a birdhouse that is 1 foot wide, 2 feet tall and 2 feet deep. Jake builds a birdhouse that is 16 inches wide, 20 inches tall and 18 inches deep. What is the difference in volume between the two birdhouses?
Answer: To compare volumes, the measurements must be in the same units. There are 12 inches in 1 ft, so Sara's birdhouse is 1 ft x 12 inches / ft = 12 inches wide, 2 ft x 12 inches / ft = 24 inches tall, and 2 ft x 12 inches / ft = 24 inches deep. The volume of Sara's birdhouse is 12 inches x 24 inches x 24 inches = 6,912 cubic inches. The volume of Jake's birdhouse is 16 inches x 20 inches x 18 inches = 5,760 cubic inches. The difference between the two birdhouses is 6,912 cubic inches 5,760 cubic inches = 1,152 cubic inches. The answer is 1152.
