Question

Diners frequently add a 15% tip when charging a meal to a credit card. What is the total amount charged if the cost of the meal, without tip, is $25? The total cost is $...

Answer 1

Given:

tip = 15%

Cost without tip = $25

The total amount charged would be:

`=\text{ 115 \% of cost without tip}`

Hence:

`\begin{gathered} =\text{ }(115)/(100)\text{ }*\text{ 25} \\ =\text{ 28.75} \end{gathered}`

Answer: The total cost is $ 28.75
