Explanation:

Let's solve problem 30: $1,760 at 7% for 2 years. We use the simple interest formula $I = P \times r \times t$, where $P$ is the principal amount, $r$ is the annual interest rate (in decimal), and $t$ is the time in years.

Step 1: Identify the values

$P = 1760$, $r = 7\% = 0.07$, $t = 2$.

Step 2: Plug into the formula

$I = 1760 \times 0.07 \times 2$. First, calculate $1760 \times 0.07 = 123.2$. Then, $123.2 \times 2 = 246.4$.

Answer:

The simple interest is $246.40.
