Answer:

B.

Explanation:

The most likely reason for this would be that the account balances are represented using a fixed number of bits, resulting in round-off errors. Since all of the numbers being used are real numbers they would have a fixed 32 bits of data. When these values are multiplied or divided they can be irrational numbers that never end, and therefore are cut off in order to fit the available data. This would cause the numbers to be rounded and can lead to the answer being imprecise.

Yanka [14]
First, you divide $71,000 by 12, to get the salary per month.

$71,000 / 12 = $<span>5,916.66.

Next, you divide the amount in a month by 2, to see how much money is paid for each half of a paycheck.

$5,916.66 / 2 = $2,958.33

Since the payment for every paycheck is $2,958.33, the answer is D.</span>
