Explanation:

1- If the investment lasts 5 years, with an interest of 6% and a principal of $ 720,00, the interest generated at the end of said investment arises from the following calculation:

(720 x 0.06) x 5 = X

43,20 x 5 = X

216 = X

Therefore, after 5 years of investment, they will have earned $ 216 in interest.

2- If the investment lasts 5 months, with an interest of 6% and a principal of $ 720, the interest generated at the end of said investment arises from the following calculation:

(720 x 0.06) / 12) x 5 = X

43.20 / 12 x 5 = X

3.6 x 5 = X

18 = X

Therefore, after 5 months of investment, they will have earned $ 18 in interest.

3- If the investment lasts 5 days, with an interest of 6% and a principal of $ 720, the interest generated at the end of said investment arises from the following calculation:

(720 x 0.06) / 365) x 5 = X

43.20 / 365 x 5 = X

0.118 x 5 = X

0.59 = X

Therefore, after 5 days of investment, $ 0.59 in interest will have been earned.

4- If the investment lasts 15 months, with an interest of 6% and a principal of $ 720, the interest generated at the end of said investment arises from the following calculation:

(720 x 0.06) / 12) x 15 = X

43.20 / 12 x 15 = X

3.6 x 15 = X

54 = X

Therefore, after 15 months of investment, they will have earned $ 54 in interest.

5- If the investment lasts 91 days, with an interest of 6% and a principal of $ 720, the interest generated at the end of said investment arises from the following calculation:

(720 x 0.06) / 365) x 91 = X

43.20 / 365 x 91 = X

0.118 x 91 = X

10.77 = X

Therefore, after 91 days of investment, you will have earned $ 10.77 in interest.
