Answer:
$8.50
Step-by-step explanation:
let the price before tax be $x
given that the sales tax rate is 4%, hence the amount she paid in taxes
= 4% of x
= (4/100)x
= 0.04x
We can now build an equation for what she paid:
Amount Paid = price before tax + amount paid in taxes
8.84 = x + 0.04x
8.84 = 1.04x (divide both sides by 1.04 and rearranging)
x = 8.84 / 1.04
x = $8.50
11)x+y=-2. 12)y=2x+1
2x-y=5. 2y=x +17
————— —————
y=1/3x+3 3y=3x÷3+18÷3
y=1x+6
if you have a problem similar to these that I did for you you just add the x variables and the y variables (if the y variable has any ) and divide the y variable with the 1st and 2nd variable
and you get the y=mx+b equation if you need the x variable too you multiply the y variable answer with the number beside it
