At a restaurant there is 7% sales tax. If the bill was $8.64, how much would he be owed in total?
Andreas93 [3]
Ok, so in order to get tax on something you multiply the amount by the amount of tax in decimal form and then add back the original amount. So for this, you'd start with 8.64*0.07, which equals 0.6048. This rounds to 0.60. 8.64+0.60=9.24

So, he would owe $9.24 total.

ddd [48]

Therefore,

Michal’s = 3 1/2 x 4.5

= 31.5/5

= 6.3 = 6.30 to the nearest hundredth

-2x-9y=-25 -4x-9y=-23
goldfiish [28.3K]
So to start this off you would add 9y to both sides of the equation and then you regroup it which gives you <span>−2x=−25+9y and then you regroup the terms and get -2x=9y-25 and then you dived both sides by -2 and get x=9y-25/-2 then you simplify and so on 

but at the end you should get x=-1 and y =3
