A lunch bill is $12 before tax. If the tax on the bill is 7.5% what is the total cost of the lunch including tax?

nikitadnepr [17]

Answer:

$\boxed{ \bold{ \huge{\boxed{ \sf{ \: 12.9 \: \: dollars}}}}}$

Step-by-step explanation:

Given,

Cost without tax = $ 12

Tax percent = 7.5 %

Cost including tax = ?

First, finding the tax amount :

$\sf{tax \: amount \: = \: 7.5 \: \% \: of \: 12}$

⇒ $\sf{tax \: amount = \frac{7.5}{100} \times 12}$

⇒ $\sf{tax \: amount = 0.9}$ dollars

Finding the total cost of the lunch including tax :

⇒ $\sf{total \: cost \: = \: 12 + 0.9}$

⇒ $\sf{total \: cost \: = \: 12.9}$ dollars
