**Answer:**

Kate's age is 6. Marcia's age is 18.

**Step-by-step explanation:**

Let Kate's's age = k

Marcia is 3 times older, so Marcia's age is 3k.

The difference in ages is 3k - k.

We are told the difference in ages is 12, so

3k - k = 12

2k = 12

k = 6

Kate's age is 6.

3k = 3(6) = 18

Marcia's age is 18.

<h3>So,</h3>

<em>Thus, Option B is the correct choice!!~</em>

The <u><em>**correct answer**</em></u> is:

D) $383.50.

**Explanation**:

Since the premium increased by 18%, that means Jordy will be paying 100% of what he paid before plus another 18%; 100%+18% = 118%.

To find 118% of $325, first we convert the percent to a decimal. 118% = 118/100 = 1.18.

Next we multiply: 1.18(325) = $383.50.
