Answer 1

Answer:

Total amount = $6125

Step-by-step explanation:

Given the following data;

Principal = $5000

Interest rate = 7.5%

Time = 3 years

To find the simple interest;

Mathematically, simple interest is calculated using this formula;

$S.I = \frac {PRT}{100}$

Where;

S.I is simple interest.

P is the principal.

R is the interest rate.

T is the time.

Substituting into the equation, we have;

$S.I = \frac {5000 * 7.5 * 3}{100}$

$S.I = \frac {112500}{100}$

S.I = $1125

Next, we find the total amount to be paid back;

Total amount = principal + simple interest

Total amount = 5000 + 1125

Total amount = $6125
