Jesse buys his coworkers lunch from the local steakhouse. The food costs $115.31 with sales tax. Jesse wants to leave a 20% tip. How much will the total be, including tip?

Answer 1

To calculate the total amount Jesse will spend, including the tip, follow these steps:

1. Find the amount of the tip:

   • The food cost with tax is $115.31.
   • Calculate 20% of $115.31: \[ \text{Tip} = 0.20 \times 115.31 = 23.062 \]

2. Round the tip if necessary:

   • For practical purposes, we can round the tip to two decimal places: \[ \text{Tip} \approx 23.06 \]

3. Add the tip to the original cost:

   • Total amount spent: \[ \text{Total} = 115.31 + 23.06 = 138.37 \]

Thus, the total amount that Jesse will pay, including the tip, is $138.37.
