Question

A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even​ number, you get a 10​% discount on your purchase that day. If the card is an odd number greater than​ 6, you get a 40​% discount.​ Otherwise, you get a 20​% discount. The table shows the results of 400 customers. What is the relative frequency for each​ discount? Use pencil and paper. If the manager of the store wants approximately half of the customers to receive the 20​% ​discount, does this seem like an appropriate​ method? Explain.

Answer 1

The answer would be A. 1 1/5

48/40 = 1 8/40

1 8/40 Simplify to 1 1/5

Hope this helps!
