Question

you need to purchase a textbook for nursing school. the book cost 80.00 and the sales tax is 8.25 where you are purchasing the book if you have $100 how much change will you receive back

Answer 1

is the tax $8.25? or is that supposed to be: 8.25% ??

Answer 2

yes the tax is 8.25

Answer 3

ill assume its (%)

80 + 80(decimal of percent) = total cost:

$100 - total cost = change back.

80 + 80(.0825) = Tc

80(1+.0825) = Tc

80(1.0825) = Tc

100 - 80(1.0825) = change back

13.40 is what youll get back if the tax is 8.25%

Answer 4

ok hold on let me process all of it lol

Answer 5

ok so when you say $100.00- total cost does that look like this 100.00-80.00

Answer 6

it looks kind of like that.

We can look at it this way to:

$100 - (book price) - (taxes paid on book price)

The $100 is money you used to pay for the book; so we are expecting change back for it right?

Answer 7

100 - 80 - (taxes) = change gotten back

Answer 8

yes

Answer 9

ooo ok let me work it out on my own and ill let you know what i get thank you :D

Answer 10

80 x 1.0825-100=13.40

Answer 11

i gotta head to marketing class now; and study for a macroeconomics exam afterwards.... Ciaobella :)

Answer 12

you just subtract the total cost out of the $100 ( I am assuming a tax of $8.25 in each book)..
100-the total cost= change back... the total cost=80+8.25=88.25
therefor the change back=100-88.25=11.75

Answer 13

simply:
100-(80+8.25)=11.75
