15.99+x=17.45 .. ?

xapproachesinfinity · Answer

think of it like this 
$\large \rm 15.99+(15.99.a)=17.45$
if you paid 4$ for a purchase with sales tax of 7percent
that mean you will pay 4+4x0.07=4.28$
in general if the sales tax is x or a or call it what ever
if you the disk is 15.99 with the sales that it will be that amount add to it 15.99xa

you will find a decimal number
multiply it by 100 to get your percentage

? did you find the answer

xapproachesinfinity · Answer

wrong

xapproachesinfinity · Answer

how did you get that

xapproachesinfinity · Answer

i see you used a wrong equation that's why you got it wrong
i said use this one
15.99+15.99x=17.45
solve for x to find your decimal number
and then transfer it to percentage by multiplying by 100

I bet you didn't read my comment?

xapproachesinfinity · Answer

Do you know how to solve this kind of equation
15.99+15.99x=17.45

anonymous · Answer

I got 31.98 now i added 15.99+15.99

xapproachesinfinity · Answer

what?
do you know how to solve 3+5x=1

anonymous · Answer

so when you find the decimal point it would be 0.08 * 100 = 8?

xapproachesinfinity · Answer

you know what forgot that
let's do it the way we do it in real life
i paid 17.45$ in total
the chair costs 15.99
so the extra tax that i paid is 1.46
now how much percent is 1.46 of 15.99
to find out we just divd 1.46 by 15.99
then we get 0.091
in percentage it will be 9.1% rounding to the nearest 10th percent
that is 9%
