After spending $75.64 at one store and $22.43 at the next store, how much money does a shopper who started with $100.00 have left?
- A. $1.93
- B. $5.00
- C. $0.72
- D. $20.13
Correct Answer: A
Rationale: To determine the remaining amount of money the shopper has, subtract the total spent ($75.64 + $22.43) from the initial amount of $100.00: $100.00 - $75.64 - $22.43 = $1.93. Therefore, the correct answer is A, $1.93, which represents the money left after the shopper's purchases. This calculation ensures that the shopper's expenses are subtracted accurately from the starting amount, providing the correct remaining balance.

Convert 2100 to standard time =
- A. 9:00 PM
- B. 2:00 AM
- C. 2:00 PM
- D. 12:00 PM
Correct Answer: A
Rationale: To convert military time to standard time, subtract 12 hours if the time is after 12:00 PM. In this case, 2100 - 1200 = 900, which is equivalent to 9:00 PM in standard time notation. Remember that military time uses a 24-hour clock, where 2100 hours is equivalent to 9:00 PM in standard time format. Therefore, the correct answer is 9:00 PM.
Convert 8:44 P.M. to military time. (Enter the numerical value only.)
- A. 2044
- B. 2204
- C. 1844
- D. 2040
Correct Answer: D
Rationale: Correct Answer: D (2040)
Rationale:
1. Military time follows a 24-hour clock.
2. To convert 8:44 P.M. to military time, add 12 hours to the given time.
3. 8 + 12 = 20, so the hour becomes 20.
4. The minute remains the same, so it is 44.
5. Therefore, 8:44 P.M. in military time is 2044.
Summary:
A: 2044 - Incorrect, same as the correct answer but not in the 24-hour clock format.
B: 2204 - Incorrect, it would be the military time for 10:04 P.M.
C: 1844 - Incorrect, it is the original time in the 12-hour clock format, not converted to military time.
A newborn's birth weight is recorded as 6,067 grams, and there are 453.59 grams in a pound. What is this infant's weight in pounds and ounces?
- A. 6 pounds, 13 ounces
- B. 13 pounds, 6 ounces
- C. 10 pounds, 13 ounces
- D. 6 pounds, 6 ounces
Correct Answer: B
Rationale: To convert 6,067 grams to pounds, divide by 453.59, giving 13.36 pounds. To find ounces, subtract the whole pounds (13) and multiply the decimal portion (0.36) by 16 (ounces in a pound), resulting in 5.76 ounces. Therefore, the infant's weight is 13 pounds and 5.76 ounces, which rounds to 13 pounds, 6 ounces (option B). Option A is incorrect as it doesn't account for the decimal portion of the pound. Option C is incorrect as it overestimates the weight. Option D is incorrect as it underestimates the weight by not considering the decimal portion.
A farmer has 240 acres under cultivation at $188.99 per acre. If he averages 60 bushels/acre, what is the expected profit if the price per bushel is $5.67?
- A. $30,000
- B. $36,290.40
- C. $40,000
- D. $45,000
Correct Answer: B
Rationale: To calculate the expected profit, first find the total cost: 240 acres * $188.99 = $45,357.60. Then, determine the total revenue: 240 acres * 60 bushels/acre * $5.67/bushel = $81,648. Subtract the total cost from the total revenue to find the profit: $81,648 - $45,357.60 = $36,290.40. Therefore, the expected profit is $36,290.40.
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.
