To find the interest earned by Rishi on his savings account, we will use the formula for simple interest, which is given by:
\[
I = P \times r \times t
\]
Where:
- \( I \) = interest earned
- \( P \) = principal balance (initial amount)
- \( r \) = interest rate (as a decimal)
- \( t \) = time in years
Given the following information:
- Principal balance \( P = 200 \) dollars
- Interest rate \( r = 0.8\% = 0.008 \) (converting percentage to decimal)
- Time \( t \) (not specified in the question, assuming it is 1 year for this calculation)
Substituting the values into the formula:
\[
I = 200 \times 0.008 \times 1
\]
Calculating:
\[
I = 200 \times 0.008 = 1.6
\]
Thus, the interest earned when \( t = 1 \) year is **$1.60**. If you provide a specific time \( t \) in years, I can calculate the interest for that duration as well.
