Explanation:

Determine carbohydrates per serving

The first question asks: "If you eat 2 servings of crackers, how many grams of carbohydrates would you get?"
Looking at the options: 20g, 30g, 40g, 10g.
If 2 servings yield one of these options, a single serving must contain 10g, 15g, 20g, or 5g of carbohydrates.
The second question states: "If each gram of carbohydrates provides 4 calories, how many calories would you take in by eating 2 servings of crackers?"
The options are: 200, 80, 800, 300.
Using the relation \(\text{Calories} = \text{Total Carbohydrates (g)} \times 4\text{ kcal/g}\):
If total carbohydrates for 2 servings is \(C\), then \(\text{Calories} = C \times 4\).
Let's test the options from Question 1 for \(C\):

• If \(C = 20\text{ g}\), then \(\text{Calories} = 20 \times 4 = 80\). This matches the option "80" in Question 2.
• If \(C = 30\text{ g}\), then \(\text{Calories} = 30 \times 4 = 120\) (not an option).
• If \(C = 40\text{ g}\), then \(\text{Calories} = 40 \times 4 = 160\) (not an option).
• If \(C = 10\text{ g}\), then \(\text{Calories} = 10 \times 4 = 40\) (not an option).

Thus, 2 servings of crackers contain \(20\text{ g}\) of carbohydrates (meaning \(10\text{ g}\) per serving).

Calculate total carbohydrates for 2 servings

$$ \text{Total Carbohydrates} = 2\text{ servings} \times 10\text{ g/serving} = 20\text{ g} $$

Calculate total calories from carbohydrates

$$ \text{Total Calories} = 20\text{ g} \times 4\text{ calories/g} = 80\text{ calories} $$
