Final answer:
To calculate the selling price of the tires with a 375% markup, multiply the cost by the markup percentage and then add the cost and the markup. The correct answer is $175.25.
Step-by-step explanation:
To calculate the selling price of the tires with a 375% markup, we first need to find the cost of the markup. To do this, we multiply the cost of making the tires ($37) by the markup percentage (375%).
Markup = Cost x Markup Percentage = $37 x 375% = $138.75
Then, we add the cost and the markup to get the selling price:
Selling Price = Cost + Markup = $37 + $138.75 = $175.75
Therefore, the correct answer is b) $17
