Dianelys owns a small business selling ice-cream. She knows that in the last week 14 customers paid cash, 121 customers used a debit card, and 3 customers used a credit card.

Question

If next week, she is expecting 1100 customers, about how many would you expect to pay with cash? Round your answer to the nearest whole number.

Answer 1

To find the estimated number of customers who will pay with cash next week, we can calculate the proportion of customers who paid with cash last week and apply it to the expected number of customers next week.

Proportion of customers who paid with cash last week:
Number of customers who paid with cash = 14
Total number of customers last week = 14 (cash) + 121 (debit) + 3 (credit) = 138
Proportion = 14/138 = 0.1014492754

Estimated number of customers paying with cash next week:
Expected number of customers next week = 1100
Estimated number of customers paying with cash next week = 0.1014492754 * 1100 ≈ 112

Therefore, we would expect approximately 112 customers to pay with cash next week.
