To calculate the simple interest earned, you can use the formula for simple interest:
\[ I = P \times r \times t \]
where:
- \( I \) is the interest earned,
- \( P \) is the principal amount (the initial investment),
- \( r \) is the rate of interest (as a decimal), and
- \( t \) is the time in years.
In this case:
- \( P = 1500 \) (the amount José put in the savings account),
- \( r = 0.03 \) (3% interest),
- \( t = 3 \) (the number of years).
Now plug in the values:
\[ I = 1500 \times 0.03 \times 3 \] \[ I = 1500 \times 0.09 \] \[ I = 135 \]
So, the simple interest José will earn at the end of 3 years is $135.00.
The correct answer is B. $135.00.
