Len and Kris had dinner in a restaurant. The dinner bill was $18.50.

Question

They had to pay a 5% food tax and they left a 15% tip for the waiter.
What was the total amount they paid for dinner that night?

Answer 1

First, calculate the food tax: $18.50 * 0.05 = $0.925

Then, calculate the total cost of the meal including tax: $18.50 + $0.925 = $19.425

Next, calculate the tip amount: $19.425 * 0.15 = $2.91375

Finally, calculate the total amount they paid for dinner: $19.425 + $2.91375 = $22.33875

So, Len and Kris paid a total of $22.34 for dinner that night.
