Suppose the sales tax rate is 9% and a store is offering a 15% discount. What is the total cost (including sales tax) of a taxable item that has a list price of $700?

Question

So you first have to figure out the price of the product with the sales tax because they apply that first

how do I figure that out

layshay12 · Answer

You would have to do 700 times 9%. Which would give you?

pphalke · Answer

63

layshay12 · Answer

Then you add that to your original price. now you take your new price of $763 and divid that by 15%

layshay12 · Answer

Then you subtract that number from your 763 and you'll have your discounted price

HI!!

doesn't seem right to me

misty1212 · Answer

try $$700\times 1.09\times .85$$ with a calculator

misty1212 · Answer

you do not get 432

layshay12 · Answer

That works too @misty1212 but i was never taught that way

misty1212 · Answer

yes it is

layshay12 · Answer

That's your answer

misty1212 · Answer

btw the commutative property shows that it doesn't matter what you do first, because $$1.09\times .85=.85\times 1.09$$

Exactly. It's just where I go to school we have a different style of learning curriculum
