Final answer:
Jerod and his friends will pay a total of $58.90 at the restaurant, which includes the original bill of $47.50, a sales tax of $2.85, and an 18% tip amounting to $8.55.
Step-by-step explanation:
Let's solve the question step by step. First, we calculate the sales tax added to the meal's cost. To find the sales tax, convert the percentage to a decimal and multiply it by the meal's total cost.
Sales Tax = 0.06 × $47.50 = $2.85
Next, we add the sales tax to the initial total to find the new subtotal:
New Subtotal = $47.50 + $2.85 = $50.35
Then, we calculate the tip. Assuming an 18% tip for the good service, convert this percent to a decimal and multiply by the original total cost of the meal.
Tip = 0.18 × $47.50 = $8.55
Add the tip to the new subtotal to get the final amount they will pay:
Final Total = $50.35 + $8.55 = $58.90
Therefore, including sales tax and tip, Jerod and his friends will pay $58.90 at the restaurant's register using a credit card.
