Answer 1

Answer:  Third investment is the least simple interest and Second investment is the  most earned simple interest.

Step-by-step explanation:

Since we have given that

Investment of $3,000 at 5% simple interest for 20 years .

Simple interest would be

$\dfrac{3000\times 5\times 20}{100}\\\\=\ 3000$

Investment of $1,000 at 16% simple interest for 20 years

Simple interest would be

$\dfrac{1000\times 16\times 20}{100}\\\\=\ 3200$

Investment of $3,000 at 16% simple interest for 2 years.

Simple interest would be

$\dfrac{3000\times 16\times 2}{100}\\\\=\ 960$

Hence, Third investment is the least simple interest and Second investment is the  most earned simple interest.
