Sarah sold 12 art pieces at her gallery last month. During the first week of the month, she sold the first 5 pieces at \$700 each. As demand increased later in the month, she raised the price of the remaining 7 pieces by \$60 per piece. What was the average selling price of the 12 art pieces sold last month?

Using the weighted average method, the total revenue from the first 5 art pieces is 5 multiplied by $700, yielding $3500. The remaining 7 pieces were sold at a raised price of \$760 each, so their total revenue is 7 multiplied by \$760, yielding \$5320. Adding these two amounts gives a combined total revenue of \$8820. Dividing this total revenue by the 12 art pieces sold results in an average selling price of $735.
