Joshua owns a small business selling bagels. He knows that in the last week 39 customers paid cash, 22 customers used a debit card, and 2 customers used a credit card.

If next week, he is expecting 700 customers, about how many would you expect to pay with cash? Round your answer to the nearest whole number.

To find out how many customers would pay with cash, we need to find the proportion of customers who paid cash last week and apply it to the number of customers expected next week.

The proportion of customers who paid with cash last week is 39/(39+22+2) = 39/63 = 0.619.

To find out how many customers are expected to pay with cash next week, we multiply this proportion by the total number of customers expected next week: 0.619 * 700 = 432.3.

Therefore, we would expect about 432 customers to pay with cash next week. Rounded to the nearest whole number, that would be 432 customers. Answer: \boxed{432}.
