Answer:
Transaction fee is $1.95 approximately.
Explanation:
Let the jewellrey costs $x before transaction fee.
So, we can set up equation for the given information as
x + 4% (x) = 50.75
Convert 4% to decimal by dividing it by 100.
x + 0.04 x=50.75
Simplify the left side of the equation.
1.04 x= 50.75
Divide both sides by 1.04
x= $48.7980..
So, transaction fee = 4% (48.7980)=$1.95 approximately.
