Find the balance of a savings account at the end of 10 years old if the interest earned each year is 7.5% the principal is $500
Am going to assume simple interest.
Interest, I = PRT/100.
Where P = Principal, R = Rate per year, T = time in years
Interest, I = 500 7.5 10 / 100 = 375
So the balance would be the amount in the account. That would be:
Principal + Interest
500 + 375
= 875
Balance = $875.
