Your answer is right.

Sorry Ms. Sue. I put your name in by mistake.

To find out if the answer is correct, we need to calculate the percentage of transactions that are NOT credit card sales.

First, we need to find the percentage of credit card sales. We know that three out of every seven sales transactions are on credit cards, so the fraction of credit card sales is 3/7.

To find the percentage, we divide the numerator (3) by the denominator (7) and multiply by 100:

(3/7) * 100 = 42.9%

So, the percentage of credit card sales is 42.9%.

To find the percentage of transactions that are NOT credit card sales, we subtract the percentage of credit card sales from 100%:

100% - 42.9% = 57.1%

Therefore, the answer, 57.1%, is correct.
