Question

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**.
