Question

Last month, Lana sold 35 necklaces a week at $15 each. However, throughout the month, 6 customers returned their necklaces for a full refund due to defective clasps. How much did Lana make selling necklaces last month?

 (Hint: Assume there were 4 weeks in the last month.)

Answer 1

There are several ways to do this problem. Here is one.

35x4=140 sold per month

140-6=134 sold after accounting for returns

134x15=$2,010 in sales
