The table below shows the amount of money needed to buy certain amounts of fabric.

To determine the cost of 12 yards of fabric, we first need to analyze the pattern from the given table of fabric costs.

From the data provided:

- 3 yards cost 5 dollars.
- 5 yards cost 10 dollars.
- 6 yards cost 9 dollars.
- 10 yards cost 15 dollars.
- 9 yards cost 15 dollars.

Let's calculate the cost per yard for the known quantities:

1. For 3 yards at 5 dollars:
Cost per yard = 5 / 3 ≈ 1.67 dollars/yard

2. For 5 yards at 10 dollars:
Cost per yard = 10 / 5 = 2 dollars/yard

3. For 6 yards at 9 dollars:
Cost per yard = 9 / 6 = 1.5 dollars/yard

4. For 10 yards at 15 dollars:
Cost per yard = 15 / 10 = 1.5 dollars/yard

5. For 9 yards at 15 dollars:
Cost per yard = 15 / 9 ≈ 1.67 dollars/yard

It appears that there are different prices from the samples provided, and we need to determine the cost for 12 yards.

To find a reasonable estimate, let's assume that the cost per yard stabilizes around the average of the previous costs identified.

Calculating average prices:
- From the data above:
- 5 / 3 = 1.67
- 10 / 5 = 2
- 9 / 6 = 1.5
- 15 / 10 = 1.5
- 15 / 9 = 1.67

The average seems to cluster around an estimate of 1.5 to 2 dollars per yard.

Now let’s calculate the cost of 12 yards at both prices.

**If cost is 1.5 dollars/yard:**
Cost for 12 yards = 12 * 1.5 = 18 dollars

**If cost is 2 dollars/yard:**
Cost for 12 yards = 12 * 2 = 24 dollars

Looking at the options provided:
1. 18 dollars
2. 20 dollars
3. 24 dollars
4. 25 dollars

There are two possible answers, but considering the deduction:

Based on the cost calculations and the average price, the best conclusion is that **the cost for 12 yards of fabric is 24 dollars.**
