**Given Information:**
- Cost of 1 kg rice = $24.25
- Weight of rice = 15.1 kg

**Calculation:**

To find the cost of 15.1 kg of rice, we can use the concept of proportions.

We know that the cost of rice is directly proportional to its weight. In other words, if the weight of rice increases, the cost also increases proportionally.

To set up the proportion, we can use the formula:

(Cost of 1 kg rice) / (Weight of 1 kg rice) = (Cost of 15.1 kg rice) / (Weight of 15.1 kg rice)

Plugging in the given values, we have:

$24.25 / 1 kg = (Cost of 15.1 kg rice) / 15.1 kg

**Simplifying the equation:**

We can simplify the equation by cross-multiplying:

$24.25 * 15.1 kg = (Cost of 15.1 kg rice) * 1 kg

365.975 = (Cost of 15.1 kg rice)

**Final Answer:**

The cost of 15.1 kg of rice is $365.975.
