Answer:
$0.29 per hour
Explanation:
To deduct 1.45% from $20 per hour you must multiply it.
So 20x0.0145=0.29
So the taxes take 29 cents per hour
To know what she earns with the tax reduction in place you subtract what they reduce from the $20 she earns
This means that with tax deduction she earns $19.71 per hour
