On a deposit of $50 at a simple interest rate of 9%, how much interest will you earn after 12 vears?

Answer: Interest after 12years is $54

Step-by-step explanation:

Simple interest (I) is calculated by Principal x Rate x Time

From the question given, Principal = $50; Rate = 9% = 9/100 = 0.09

Time = 12years

Slot the values into the formula

I = $50 x 0.09 x 12

I = $54

I hope this is clear, do have a great day!
