Step-by-step explanation:

Given that:

Mr. Stripling needs to take out a loan of $20,000 to be able to pay for his Graduate course.

That means , he needs a principal amount of $20,000

SO , he has two options;

A - To borrow from Union Hill Bank which offers him 7% interest for 3 years.

B - To borrow from Emerson Bank which offers him  5% interest in 4 years

For Bank A; (Union Hill Bank)

Let Principal = $20,000

Rate = 7%

T = 3 years
