The amount of sales tax that is taken on the camera = $5.60
Percentage of sales tax taken on the camera = 8%
Let us assume the actual price of the camera = x dollars
Then
(8%) * x = 5.60
(8/100) * x = 5.60
2x/25 = 5.60
2x = 5.60 * 25
2x = 140
x = 140/2
= 70 dollars
So the actual price of the camera is $70. I hope the procedure is clear enough for your understanding. You can use this method for solving similar problems in future without requiring any help from outside.
