An XBOX 360 regularly sells for $399. It is on sale for 20% off. What is the sale price of the XBOX 360? A) $78.80 B) $300.00 C) $319.20 D) $391.02

OpenStudy (misssmartiez):

0.20 x 399.

OpenStudy (mariakershaw):

yea ^

OpenStudy (misssmartiez):

You just construct the percent to a decimal. 20% / 100 = 0.20.

OpenStudy (anonymous):

79.8%

OpenStudy (misssmartiez):

or in other words, 0.2. Now complete the process.

OpenStudy (mariakershaw):

agree @MissSmartiez

OpenStudy (anonymous):

So, "A"?

OpenStudy (mariakershaw):

yup

OpenStudy (misssmartiez):

It equals 79.80 so yes.

OpenStudy (misssmartiez):

OpenStudy (anonymous):

Thank you.

OpenStudy (mariakershaw):

welcome @parisjackson

OpenStudy (misssmartiez):

You aren't done yet. 79.8. move the decimal point over two spaces. 7980%

OpenStudy (misssmartiez):

Though it would be invalid in this term, so just leave it to a decimal.

OpenStudy (anonymous):

Aw, thank you @MissSmartiez

OpenStudy (mariakershaw):

yup agree with @MissSmartiez
