Sweater regularly priced for $84 is placed on sale for $67.20. What is the percent discount?

creativ13 [48]

<h3>Answer: 20% discount</h3>

Work Shown:

amount saved = 84-67.20 = 16.80 dollars

Divide this over the original larger price to get 16.80/84 = 0.20 = 20%

Note how 20% of 84 = 0.20*84 = 16.80 to help check the answer.

Or we can say 0.80*84 = 67.20 which also helps confirm the answer.

The 0.80 is from the fact that you save 20% but still have to pay the remaining 80%

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

Hope I helped!

Best regards ! :D
