Final answer:
To find the total payment at the restaurant, including sales tax and tip, calculate 6% sales tax on $47.50, and then add a 15% tip on the original amount. The total comes to $57.48.
Step-by-step explanation:
Jim should be arrested for theft, specifically, for "dine and dash", a term used when someone consumes food at a restaurant and leaves without paying. However, to address the mathematical part regarding Jerod and his friends' situation, let's calculate their total bill including sales tax and tip at a restaurant.
First, calculate the sales tax: $47.50 × 0.06 = $2.85. Add this to the subtotal to find the total before tip: $47.50 + $2.85 = $50.35. If Jerod and his friends decide to leave a 15% tip on the original amount (before tax), it would be $47.50 × 0.15 = $7.13. Now, add the tip to the total after the tax to find out what they will pay: $50.35 + $7.13 = $57.48.
Therefore, if Jerod and his friends use a credit card to pay, they will pay $57.48 at the restaurant's register, including sales tax and tip.
