1. To determine which food supplies more than one-quarter of the daily intake of 1,700 to 1,800 calories, we first calculate one-quarter of this range:
- One-quarter of 1,700 calories = 425 calories
- One-quarter of 1,800 calories = 450 calories
Now, we examine the high-calorie, high-fat foods listed:
- Vanilla soft-serve ice cream has 185 calories.
- French fries have 458 calories.
The only food that meets the requirement of providing more than one-quarter (425-450 calories) of the daily intake is **French fries** at 458 calories.
To balance the eating plan over the course of the day, you might consider incorporating lower-calorie, nutrient-dense options, such as:
- Vanilla frozen yogurt (114.5 calories)
- Pretzels (108 calories)
- Fresh fruits and vegetables
- Lean proteins such as grilled chicken or fish
- Whole grains like brown rice or quinoa
2. To compare the calories from fat in each snack, we can use the formula:
Calories from fat = grams of fat × 9 calories/gram
For each snack:
- **Vanilla soft-serve ice cream**:
- Fat: 11.2 g
- Calories from fat: 11.2 g × 9 = 100.8 calories from fat
- **Vanilla frozen yogurt, soft serve**:
- Fat: 4 g
- Calories from fat: 4 g × 9 = 36 calories from fat
**Comparison**:
- Vanilla soft-serve ice cream provides **100.8 calories from fat**.
- Vanilla frozen yogurt provides **36 calories from fat**.
Thus, the soft-serve ice cream has significantly more calories from fat than the soft-serve yogurt.
- One-quarter of 1,700 calories = 425 calories
- One-quarter of 1,800 calories = 450 calories
Now, we examine the high-calorie, high-fat foods listed:
- Vanilla soft-serve ice cream has 185 calories.
- French fries have 458 calories.
The only food that meets the requirement of providing more than one-quarter (425-450 calories) of the daily intake is **French fries** at 458 calories.
To balance the eating plan over the course of the day, you might consider incorporating lower-calorie, nutrient-dense options, such as:

2. To compare the calories from fat in each snack, we can use the formula:
Calories from fat = grams of fat × 9 calories/gram
For each snack:
- **Vanilla soft-serve ice cream**:
- Fat: 11.2 g
- Calories from fat: 11.2 g × 9 = 100.8 calories from fat
- **Vanilla frozen yogurt, soft serve**:
- Fat: 4 g
- Calories from fat: 4 g × 9 = 36 calories from fat
**Comparison**:
- Vanilla soft-serve ice cream provides **100.8 calories from fat**.
- Vanilla frozen yogurt provides **36 calories from fat**.
Thus, the soft-serve ice cream has significantly more calories from fat than the soft-serve yogurt.
