Question: Noah is a painter. He paints pictures and sells them at the park. He charges $60 for a large painting and $30 for a small painting. Last month he sold eight large paintings and four small paintings. If he sold twice as much this month, how much is his sales for this month?
Answer: Step-by-step reasoning process: Noah earned $60 / large painting x 8 large paintings = $480 for the large paintings. He also earned $30 / small painting x 4 small paintings = $120 for the small paintings. His total sales last month were $480 + $120 = $600. So, his sales this month are $600 x 2 = $1200.
So the answer is 1200.

Question: Kristy, a sales representative earns a basic salary of $7.50 per hour plus a 16% commission on everything she sells. This month, she worked for 160 hours and sold $25000 worth of items. Her monthly budget for food, clothing, rent, transportation, bills and savings is 95% of her total monthly earnings and the rest will be put towards insurance. How much did she allocate to insurance?
Answer: Step-by-step reasoning process: Kristy earns a basic salary of $7.50 x 160 = $1200. Her total commission is $25000 x 16 / 100 = $4000. Thus, her total earning is $1200 + $4000 = $5200. Her monthly budget aside from the insurance is $5200 x 95 / 100 = $4940. Therefore, she allocated $5200 - $4940 = $260 on insurance.
So the answer is 260.

Question: Carter is twice as tall as his 24” tall dog. Betty is 12” shorter than Carter. How tall is Betty in feet?
Answer: Step-by-step reasoning process: Carter is twice as tall as 24” dog so he is 2 * 24 = 48”. Betty is 12” shorter than Carter so Betty is 48 - 12 = 36” tall. 12" is the same as 1 foot so Betty is 36 / 12 = 3 feet tall.
So the answer is 3.

Question: Karen packs peanut butter sandwiches in her daughter's lunch 2 randomly chosen days of the week. The other 3 school days, she packs a ham sandwich. She packs a piece of cake on one randomly chosen day and cookies the other four days. What is the probability, expressed as a percentage, that Karen packs a ham sandwich and cake on the same day?
Answer:
Step-by-step reasoning process: There are 5 school days in a week, so the probability Karen packs a ham sandwich is 3 / 5 and the probability she packs cake is 1 / 5. Multiply the two probabilities to find the probability both things happen: 3 / 5 * 1 / 5 = 3 / 25. Now divide 3 by 25 and multiply by 100% to express this probability as a percentage: 3 / 25 * 100% = 12%.
So the answer is 12.
