#### Principal (initial amount), P = 2,375,000

#### Due interest, I = 475,000

#### Annual simple interest rate, R = 10%

#### Commission fee (withdrawal or payment), F = 0%

#### No. of days in a year, N = 365

## T = The investment duration period, in days:

#### T = (N × I) ÷ (P × R) =

#### (365 × 475,000) ÷ (2,375,000 × 10%) =

#### (365 × 475,000) ÷ (2,375,000 × ^{10}/_{100}) =

#### (100 × 365 × 475,000) ÷ (2,375,000 × 10) =

#### 17,337,500,000 ÷ 23,750,000 =

#### 730

#### T = 730 days

## B = Amount earned:

#### B = P + I =

#### 2,375,000 + 475,000 =

#### 2,850,000
