Final answer:
To calculate the total bill at the restaurant's register, add the food cost, sales tax, and tip amount.
Step-by-step explanation:
The question seems to be about a bill and paying for items at a restaurant. To find out how much Jerod and his friends will pay at the restaurant's register, we need to calculate the total bill including sales tax and tip. The total bill is the sum of the food cost, the sales tax, and the tip amount.
First, we calculate the sales tax by multiplying the food cost by the tax rate (6% or 0.06). Then, we calculate the tip amount based on the percentage they decide to leave. Finally, we add the food cost, sales tax, and tip amount to find the total bill.
