Answer:
The interest is 450 ⇒ C
Step-by-step explanation:
The formula of the simple interest is I = Prt, where
- P is the investment amount
∵ Birr invested 2500 at 6% simple interest per annum for 3 years
∴ P = 2500
∵ r = 6%
→ Divide it by 100 to change it to decimal
∵ 6% = 6 ÷ 100 = 0.06
∴ r = 0.06
∴ t = 3
→ Substitute them in the formula above
∵ I = 2500 × 0.06 × 3
∴ I = 450
∴ The interest is 450
