Question

The following bond was quoted in The Wall Street Journal: Five bonds were purchased yesterday, and 5 bonds were purchased today. How much more did the 5 bonds cost today? Note: Do not round intermedia

Answer 1

To determine the difference in cost, divide the total cost of the 5 bonds purchased today by 5, then subtract the cost of each bond purchased previously. If the cost of each bond purchased yesterday was $100 and the cost of each bond purchased today is $120, the difference would be $100.

Step-by-step explanation:

In order to determine how much more the 5 bonds cost today compared to the previous purchase, we need information about the cost of each bond. If we assume that the cost of each bond is the same, we can divide the total cost of the 5 bonds purchased today by 5 to find the cost of each bond. Then, we can subtract the cost of each bond from the cost of each bond purchased previously, to find the difference.

For example, if the cost of each bond purchased yesterday was $100 and the cost of each bond purchased today is $120, the 5 bonds would cost $500 yesterday (5 x $100) and $600 today (5 x $120), resulting in a difference of $100 ($600 - $500).

Answer 2

The difference in cost for the 5 bonds purchased today compared to the previous purchase is $100.

Calculate the total cost of 5 bonds purchased today:

If the cost of each bond purchased today is $120, then the total cost of 5 bonds today would be 5 * $120 = $600.

Calculate the difference in cost:

Subtract the total cost of the 5 bonds purchased yesterday from the total cost of the 5 bonds purchased today.

If the cost of each bond purchased yesterday was $100, then the total cost of 5 bonds yesterday would be 5 * $100 = $500.

The difference is $600 (today) - $500 (yesterday) = $100.

Therefore, the correct difference in cost for the 5 bonds purchased today compared to the previous purchase is $100.
