Q: 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?
A: 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: Farmer Steven needs to load his truck up with compost. His tractor can scoop up compost at a rate of 75 pounds per minute. Steven's son, Darrel, wants to help. Using a shovel, Darrel can scoop up 10 pounds per minute. How much time, in minutes, would it take for the two working together at the same time to load up 2550 pounds of compost into the truck?
Answer: Working together at the same time, the rate at which the two would be able to load compost would be 75 + 10 = 85 pounds / minute. At 85 pounds / minute, the 2550 pounds could be loaded in 2550 / 85 = 30 minutes. The answer is 30.
[Question]Josh buys 3 packs of string cheese. Each piece of string cheese cost 10 cents. Each pack has 20 string cheeses in them. How many dollars did he pay?
[Answer]Each pack cost 20 * 10 = 200 cents. So each pack cost 200 / 100 = $2. That means he pays 2 * 3 = $6. The answer is 6.
Q: Three baskets A, B and C contain different numbers of differently colored marbles. Basket A contains 4 red marbles and 2 yellow marbles. Basket B contains 6 green marbles and 1 yellow marble. Basket C contains 3 white marbles and 9 yellow marbles. What is the difference between the number of each color of marble in the basket that has the greatest difference?
A: In basket A the number difference between differently colored marbles is 4 - 2 = 2. In basket B the difference is 6 - 1 = 5. In basket C the difference is 9 - 3 = 6. Comparing 2, 5 and 6 shows that 6 is the greatest difference. The answer is 6.
Question: James' keyboard is missing 1/7 of the consonants and two vowels. How many keys are missing in total? (Remember there are 5 vowels and 21 consonants in the alphabet.)
