Medal!

A store is having a 20%-off sale. It gives an additional 10% off if the item is still above $100 after the first discount. A jacket costs $149.99. Will you get the second discount and if so, how many dollars will you save?

OpenStudy (mertsj):

If the jacket is 20% off, that means you have to pay 80% of the price. What is 80% of $149.99 ?

OpenStudy (anonymous):

$30.00?

OpenStudy (mertsj):

What is 80% when written in decimal form?

OpenStudy (anonymous):

0.80

OpenStudy (mertsj):

Do you know that "of" in mathematics means "times" ??

OpenStudy (anonymous):

i didnt know that:) thanks for telling me!

OpenStudy (mertsj):

So now that you know that, find 80% OF 149.99

OpenStudy (anonymous):

i got 119.992

OpenStudy (mertsj):

Is that more than $100?

OpenStudy (anonymous):

yes:)

OpenStudy (mertsj):

Then will you qualify for the extra 10% discount or not?

OpenStudy (anonymous):

yes.

OpenStudy (mertsj):

Very good. And that is the answer to the question the problem asks.

OpenStudy (anonymous):
