The image you provided contains a few math problems. I'll analyze and solve each one for you.

### Problem 14
The problem asks to solve the equation:
\[ 6.18 = 0.618x \]
To solve for $ x $, divide both sides by 0.618:
\[ x = \frac{6.18}{0.618} = 10 \]

So, the answer is:
- **C. 10**

### Problem 15
The problem states:
"12.5 kg of sugar costs $13.75. How much does 8 kg of sugar cost?"

To find the cost per kilogram, divide the total cost by the total weight:
\[ \text{Cost per kg} = \frac{13.75}{12.5} = 1.1 \, \text{dollars per kg} \]

Now, multiply by 8 kg:
\[ \text{Cost of 8 kg} = 1.1 \times 8 = 8.8 \, \text{dollars} \]

So, the answer is:
- **A. \$8.80**

### Problem 16
This problem shows a pie chart and asks: 
"What percentage of his money did he spend on snacks?"

The pie chart shows different categories, and from the image, it looks like the portion labeled "Snacks" is 25%.

So, the answer is:
- **C. 25%**

Do you want further details or have any questions on these problems? 

Here are five related questions to expand your understanding:
1. How can you calculate percentages from a pie chart with different values?
2. What is the general approach to solving proportion problems like in question 15?
3. How would you solve a similar equation to problem 14 if the numbers were different?
4. How can you determine if a cost per unit is reasonable in real-life scenarios?
5. What other mathematical methods can be used to solve equations with decimals?

**Tip:** When solving problems with percentages or proportions, it helps to first break down the problem into smaller, more manageable parts. This ensures that you don't miss any steps in the calculation.

The image contains math problems including an equation, a proportion calculation for cost, and a percentage problem involving a pie chart.
