The customer paid $7.53 for the item
Markup is the difference between a product's selling price and cost as a percentage of the cost. It is given by:
[tex]Markup=\frac{selling\ price-cost\ price}{cost\ price} \\\\[/tex]
Markup = 115% = 1.15, cost price = $3.50, hence:
[tex]Markup=\frac{selling\ price-cost\ price}{cost\ price} \\\\1.15=\frac{selling\ price-3.5}{3.5} \\\\Selling\ price=\$7.53[/tex]
Hence the customer paid $7.53 for the item.
