Answer:
Ans. The after-tax rate of return on the municipal bonds is 3% and the after tax rate of return on the corporate bonds is 4.5%
Step-by-step explanation:
Hi, the formula to find the after-tax rate of return of any taxable income is as follows.
![r(AfterTax)=r(BeforeTax)*(1-Taxes)](https://img.qammunity.org/2020/formulas/business/college/xyd0dxfq0n0sx7d8h7afwpb7pp4oau4wfc.png)
Therefore, in the case of the municipal bond.
![r(AfterTax)=0.04*(1-0.25)=0.03](https://img.qammunity.org/2020/formulas/business/college/nbj9fyno3rchwzu5hc8viohajtp4cjpoys.png)
So, the after-tax rate of return of the municipal bond is 3%.
And for the corporate bond is.
![r(AfterTax)=0.06*(1-0.25)=0.045](https://img.qammunity.org/2020/formulas/business/college/q4m5j4gceu4y3h4fwcpqdjww1pkj9fltm1.png)
And the after-tax rate of return of the corporate bond is 4.5%.
It means that taxes on municipal bonds are:
![Taxes= Return(BeforeTax)-Return(AfterTax)](https://img.qammunity.org/2020/formulas/business/college/b2ttynwmnuykasaab1cu0rfdd9m61xr8ln.png)
In the case of municipal taxes:
![Taxes=0.04-0.03=0.01](https://img.qammunity.org/2020/formulas/business/college/40qs3gk6hl9xpjn079a8p5nnqcq3oqf2qg.png)
1% taxes for municipal bonds
In the case of corporate taxes:
![Taxes=0.06-0.045=0.015](https://img.qammunity.org/2020/formulas/business/college/hrn97utvaoestd059w10odkkcjvbkfpuic.png)
1.5% taxes for corporate bonds
Best of luck.
