Answer:
1- $216
2- $18
3- $0.59
4- $54
5- $10.77
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.
