Three of every seven sales transactions at Dollar Discount are on credit cards. What percent of the transactions are not on credit card sales?

To find the percent of transactions that are not on credit card sales, we need to calculate the fraction of transactions that are not on credit cards and then convert it to a percentage.

Given that three out of every seven sales transactions at Dollar Discount are on credit cards, we can determine that four out of every seven transactions are not on credit cards.

To convert this fraction to a percentage, divide the number of transactions not on credit cards (four) by the total number of transactions (seven), and then multiply by 100:

(4 / 7) * 100 = 57.14%

Therefore, approximately 57.14% of the transactions at Dollar Discount are not on credit card sales.
