Oct 13, 2025 by magicalceylontours.com 30 views

When dining out, it's customary to show appreciation for good service by leaving a tip for the waiter. The standard tip percentage varies, but 20 percent is a common rate. In this scenario, we're given a restaurant bill of $$ 25$ and need to determine the expression that can be used to find the total amount that will be paid, including the 20 percent tip.

Understanding the Problem

To calculate the total amount to be paid, we need to find 20 percent of the restaurant bill and then add it to the original bill amount. This will give us the total amount that needs to be paid.

Calculating 20 Percent of the Restaurant Bill

To find 20 percent of the restaurant bill, we can multiply the bill amount by 0.20. This is because 20 percent is equivalent to 0.20 as a decimal.

Expression for Finding the Total Amount

The expression to find the total amount that will be paid can be represented as:

$\$ 25 \times 1.20$

This expression takes into account the original bill amount of $\$ 25$ and adds 20 percent of that amount to it.

Evaluating the Options

Let's evaluate the given options to determine which one represents the correct expression for finding the total amount that will be paid.

Option A: $\$ 25 \times 10.02$

This option is incorrect because multiplying the bill amount by 10.02 would result in an amount that is 402 percent of the original bill, not 20 percent.

Option B: $\$ 25 \times 0.20$

This option is incorrect because multiplying the bill amount by 0.20 would result in 20 percent of the original bill, but it does not take into account the original bill amount.

Option C: $\$ 25 \times 1.20$

This option is correct because it represents the expression that takes into account the original bill amount and adds 20 percent of that amount to it.

Conclusion

In conclusion, the expression that can be used to find the total amount that will be paid is $\$ 25 \times 1.20$ . This expression accurately represents the calculation of 20 percent of the restaurant bill and adds it to the original bill amount.
