Jackson purchased a pack of game cards that was on sale for 22% off. The sales tax in his county is 6%. Let y represent the original price of the cards. Write an expression that can be used to determine the final cost of the cards.

First I would put 22% and 6% into a decimal. You can do this by dividing the numbers by 100.
@geekfromthefutur
well that would be 22.0 and 6.0
no it wouldn't be. That would be 2200% and 600%
Im confused
take 22 and divide it by 100 then take 6 and divide it by 100
0.22 0.6
you got the .22 correct not the .6 though
.6 is 60% of 1
sorry I meant 0.06
correct :) Now we don't know the price of the cards but that is alright because they gave us the variable which is y
when we multiply a number by a decimal what happens?
I forgot lol
Well try it. Multiply 100 by .22
it goes back to 22
can you hurry up I need to get this done like NOW please
Sorry made a mistake. But when we use sale rates, we multiply the number (in this case the variable y) by the percent thats taken off (22% or .22 as a decimal) When we get that number we subtract them together then multiply that number by sales tax (6% or .06 as a decimal) when we get this number we then subtract it into how much the item cost.
so whats the exact expression y x 0.22 = whatever this is x 0.06 = whatever this - y
@KlOwNlOvE
I would say \[y(.22-.06)\] or \[y(.22)^.06\]
thanks @KlOwNlOvE
