Answer this question:Sonja makes her own peanut butter with peanuts and oil in a blender. She uses a ratio of two ounces of oil to smooth out every eight ounces of peanuts. Her last batch of peanut butter weighed 20 ounces. How many ounces of oil did she use?
Sonja uses 2 ounces of oil for 8 ounces of peanuts to make 2 + 8 = 10 ounces of peanut butter. Her last batch weighed 20 ounces, so she made 20 / 10 = 2 times her ratio. Thus, she used 2 * 2 = 4 ounces of oil.
The answer is 4.

Answer this question:A new factory opens up and hires 20 people to make t-shirts. Each person makes on average 20 shirts per day during their 8-hour shift. The employees each get paid $12 an hour plus $5 per shirt they make. The company sells shirts for $35 each.  Nonemployee expenses come out to $1000 a day. How much does the company make in profits per day?
Each employee gets paid 20 * 5 = $100 for the shirts they make. They also get paid 12 * 8 = $96 for hours worked. So they get a total of 100 + 96 = $196 per day. That means employee cost is 20 * 196 = $3920. The factory makes 20 * 20 = 400 shirts. So they make 400 * 35 = $14,000 from selling shirts. So they made a profit of 14,000 - 3,920 - 1,000 = $9,080.
The answer is 9080.
