Answer:
Sales = n ($x + $y)
Step-by-step explanation:
The basic simple sales equation is
Quantity Price = Sales
Here in the given question,
Total quantity of sales = n
Price = Cost + markup
(Markup refers to the profit added to cost)

Sales = n ($x + $y)
Sales amount is the total amount received from sales of products, total quantity at some price provided.
