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
