Question

At a restaurant, you order a moal that costs $12. You leave a 15% tip. The sales tax is 9%. What is the total costof the meal In dollars

Answer 1

Case: Percentages

Given:

Meal cost= $12

tip= 15%

sales tax= 9%

Method:

To find the Total cost of the meal,

We calculate the actual cost of the tip

`\begin{gathered} 15\%*12 \\ (15)/(100)*12 \\ (180)/(100) \\ 1.8 \end{gathered}`

The actual cost of the tip was $1.80

We then calculate the actual cost of the sales tax

`\begin{gathered} 9\%*12 \\ (9)/(100)*12 \\ (108)/(100) \\ 1.08 \end{gathered}`

The cost of sales tax is $1.08

The total cost of the mean is:

`\begin{gathered} 12+1.80+1.08 \\ =14.88 \end{gathered}`

Final answer:

The total cost of the meal is $14.88
