Answer 1

To determine which costs more, we can calculate the total cost for each set of candy bars.

1. Cost of 17 candy bars at 79 cents each: \[ 17 \times 0.79 = 13.43 \text{ dollars} \]

2. Cost of 21 candy bars at 65 cents each: \[ 21 \times 0.65 = 13.65 \text{ dollars} \]

Now, comparing the two costs:

• The total cost for 17 candy bars is $13.43.
• The total cost for 21 candy bars is $13.65.

Next, we find the difference in cost: \[ 13.65 - 13.43 = 0.22 \text{ dollars} \text{ or } 22 \text{ cents} \]

Thus, the 21 candy bars cost 22 cents more than the 17 candy bars.

The correct response is: The 21 candy bars cost 22 cents more than the 17 candy bars.
