Answer this question:John assembles computers and sells prebuilt computers as a business. The parts for the computer cost $800. He sells the computers for 1.4 times the value of the components. He manages to build 60 computers a month. He has to pay $5000 a month in rent and another $3000 in non-rent extra expenses a month. How much profit does he make a month?
He sells each computer for 1.4 * 800 = $1120. That means he makes a profit of 1120 - 800 = $320 per computer. So he makes 320 * 60 = $19200 from selling computers. He has extra expenses of 5000 + 3000 = $8000 a month. So his profit is 19200 - 8000 = $11,200.
The answer is 11200.

Answer this question:Wallace's water heater is twice the size of Catherine's water heater. If the capacity of Wallace's water heater is 40 gallons and it's 3/4 full, calculate the total number of gallons of water they both have if Catherine's water heater is also full with water to 3/4 of its capacity.
When 3 / 4 full of water, Wallace's water heater has 3 / 4 * 40 = 30 gallons of water. Catherine's water heater capacity is 40 / 2 = 20 gallons. When 3 / 4 full, Catherine's water heater has 3 / 4 * 20 = 15 gallons of water. Together, when 3 / 4 full with water, Wallace's and Catherine's water heaters hold 15 + 30 = 45 gallons of water.
The answer is 45.

Answer this question:For an operations manager job at a company, a person with a degree earns three times the amount paid to a diploma holder for the same position. How much will Jared earn from the company in a year after graduating with a degree if the pay for a person holding a diploma certificate is $4000 per month?
Since the pay for a person holding a degree is three times the amount paid for a diploma holder, Jared will earn 3 * $4000 = $12000 per month. In a year with 12 months, Jared will earn a total of 12 * 12000 = 144000.
The answer is 144000.

Answer this question:Joe and Adam built a garden wall with three courses of bricks. They realized the wall was too low and added 2 more courses. If each course of the wall had 400 bricks, and they took out half of the bricks in the last course to allow easy checkup of the garden, calculate the total number of bricks the wall has.
When they added two more courses for the wall, the number of courses became 3 + 2 = 5. Since each course has 400 bricks, the total number of bricks for 5 courses is 5 * 400 = 2000. To allow for an easy checkup of the wall, they removed 1 / 2 * 400 = 200 bricks from the last course of the wall. In total, the wall has 2000 - 200 = 1800 bricks.
The answer is 1800.
