Farmer Juan has 14 acres. There is an average yield of 17,460 eggs per acre. The profit per egg is $1.65. What profit should Farmer Juan expect for 14 acres?

  • A. $403,326
  • B. $148,145.45
  • C. $244,440
  • D. $2,057.79
Correct Answer: A

Rationale: To calculate Farmer Juan's profit for 14 acres, multiply the total number of eggs (14 acres * 17,460 eggs/acre) by the profit per egg ($1.65). This computation results in: 14 * 17,460 * $1.65 = $403,326. Therefore, Farmer Juan should expect a profit of $403,326 for 14 acres. Each acre produces 17,460 eggs, and since Farmer Juan has 14 acres, the total number of eggs is 14 * 17,460 = 243,240 eggs. Multiplying the total eggs by the profit per egg ($1.65) gives the total profit: 243,240 * $1.65 = $403,326. Hence, Farmer Juan should expect a profit of $403,326 for 14 acres.

If the quotient is 4 and the dividend is 12, what is the divisor?

  • A. X
  • B. 4
  • C. 3
  • D. 12
Correct Answer: C

Rationale: To find the divisor in a division problem, you can use the formula: Dividend = Divisor x Quotient. In this case, the dividend is 12, and the quotient is 4. You can set up the equation as 12 = Divisor x 4. To isolate the divisor, you divide the dividend by the quotient. Divisor = Dividend / Quotient = 12 / 4 = 3. Therefore, the correct answer is 3. Dividing 12 by 4 gives you the divisor, which is 3. So, 3, when multiplied by the quotient of 4, equals the dividend of 12.

Change the decimal to a percent: 0.64 =

  • A. 0.64%
  • B. 64%
  • C. 6.40%
  • D. 0.06%
Correct Answer: B

What is the result of adding 9.98 and 0.065?

  • A. 10.63
  • B. 10.045
  • C. 1.0063
  • D. 998.065
Correct Answer: B

Rationale: To find the sum of 9.98 and 0.065, you align the decimal points and add the numbers as you would with whole numbers: 9.98 + 0.065 = 10.045. Therefore, the correct answer is B, which is 10.045. When adding decimal numbers, it's essential to keep the decimal points aligned to ensure an accurate sum. In this case, the sum is 10.045.

A young adult is running a 24-mile course. If they run the first 6 miles in 1 hour, the second 6 miles in 1.2 hours, the third 6 miles in 1.5 hours, and the fourth 6 miles in 1.6 hours, how long will it take them to complete the run? (Round to the nearest tenth.)

  • A. 5.3
  • B. 5.6
  • C. 5.8
  • D. 6
Correct Answer: A

Rationale: To find the total time taken to complete the 24-mile run, add the times for each segment: 1 + 1.2 + 1.5 + 1.6 = 5.3 hours. Therefore, it will take them 5.3 hours to finish the 24-mile course. The correct answer is A, 5.3 hours.
