An investor considers whether to invest in debt or equity of STU Corporation. Since he already has to pay a high personal tax rate, he does not want to pay more taxes than necessary. Therefore, he weighs the pros and cons of investing in bonds or equities in the local financial markets. The personal tax rate on interest income is 45%, the corporate tax rate is 27.5% and the tax rate on dividends is 20%. Which strategy do you recommend the investor?

I understand the investor should invest but you explain to me in detail, thank you :)
