$1,800 plus 6.5% of sales
$2,100 plus 4% of sales
What is 6.5% of $5,000?
What is 6.5% of $10,000?
What is 4% of $5,000?

A retailer (store) buys items from manufacturers at WHOLESALE/ MANUFACTURER PRICES. The retailer then sells those items to customers (you and me) at RETAIL PRICES.
The increase in price from the WHOLESALE PRICE to the RETAIL PRICE is how a store makes money. This increase is called a MARKUP.
