Camille wants to buy a new coat and gloves for her winter ski trip. She finds the perfect coat for $79.50 and matching gloves for $14.50. When she gets to the cash register she finds out that all coats are on sale for 20% off. The sales tax rate in Camille's city is 6%. What is the total amount Camille has to pay for the two items, including sales tax? Round your answer to the nearest cent.

OpenStudy (mertsj):

Now remember...if the coat is 20% off that means she has to pay 80%. So find 80% of 79.50. That will be the price of the coat.

OpenStudy (mertsj):

How much is the coat?

OpenStudy (anonymous):

why would she need 80 %?

OpenStudy (mertsj):

If she doesn't have to pay 20% then she DOES have to pay 80%

OpenStudy (anonymous):

im sorry, that just doesnt make sense to me

OpenStudy (mertsj):

So multiply .80 times 79.50. That is the price of the coat.

OpenStudy (anonymous):

and then..

OpenStudy (mertsj):

Ok. Then do it this way. The coat is 20% off. Multiply .20 times 79.50. That will be the discount. Subtract the discount from 79.50. That will be the price of the coat.

OpenStudy (mertsj):

How much is the coat?

OpenStudy (anonymous):

63.6

OpenStudy (mertsj):

Now add the price of the gloves because she is also buying the gloves.

OpenStudy (mertsj):

How much does her stuff cost?

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

78.1 $

OpenStudy (mertsj):

But of course she has to pay the 6% sales tax so multiply 78.10 by .06. That is the tax.

OpenStudy (mertsj):

How much is the tax?

OpenStudy (anonymous):

4.686

OpenStudy (mertsj):

this is money so round it to 4.69 and add it to the price of the coat & gloves. 78.10+4.69

OpenStudy (anonymous):

thanks!
