Answer:
15%
Explanation:
If Miranda works 40 hours a week at a wage rate of $25. and she however calculates that on the last hour that she works, she pays $3.75. then her marginal tax rate is derived as follows
The marginal tax rate is the incremental tax paid on incremental income.
From the scenario, we are given the following:
Weekly wage rate is $25.
Weekly tax pay is $3.75
Hence, Marginal tax rate can be computed as = $3.75 / $25 = 15%
