7 answers

To solve the problem, we need to define the variables based on the context of the meals purchased.

Let's define:

  • \( b \) as the price of a burger meal
  • \( h \) as the price of a hot dog meal

From the information given, we can set up the following equations based on the purchases made by the Johnsons and the Wilsons:

  1. For the Johnsons: \[ 2b + 5h = 46 \]

  2. For the Wilsons: \[ 5b + 2h = 52 \]

The solution (8, 6) indicates:

  • The value \( b = 8 \): This means that the price of a burger meal is $8.
  • The value \( h = 6 \): This means that the price of a hot dog meal is $6.

Now, to determine who got the better deal, we can calculate the total cost for both families based on their orders:

Johnsons:

  • 2 burger meals: \( 2 \times 8 = 16 \)
  • 5 hot dog meals: \( 5 \times 6 = 30 \)
  • Total cost for the Johnsons: \( 16 + 30 = 46 \)

Wilsons:

  • 5 burger meals: \( 5 \times 8 = 40 \)
  • 2 hot dog meals: \( 2 \times 6 = 12 \)
  • Total cost for the Wilsons: \( 40 + 12 = 52 \)

Better deal: To assess who got the better deal, we can look at the total quantity of meals purchased divided by the total cost:

  • The Johnsons bought 2 burger meals and 5 hot dog meals, totaling 7 meals. Their cost was $46. \[ \text{Cost per meal for the Johnsons} = \frac{46}{7} \approx 6.57 \]

  • The Wilsons bought 5 burger meals and 2 hot dog meals, totaling 7 meals. Their cost was $52. \[ \text{Cost per meal for the Wilsons} = \frac{52}{7} \approx 7.43 \]

Conclusion: The Johnsons got the better deal because they paid approximately $6.57 per meal, while the Wilsons paid approximately $7.43 per meal.

What does the 8 mean in context?

In context, the value \( 8 \) refers to the price of a burger meal at the Burger Barn. Specifically, it means that each burger meal costs $8. This information helps us understand the pricing structure for the meals ordered by both the Johnsons and the Wilsons.

What does the 6 mean in context?

In context, the value \( 6 \) refers to the price of a hot dog meal at the Burger Barn. Specifically, it means that each hot dog meal costs $6. This pricing information is important for understanding the total costs incurred by both the Johnsons and the Wilsons for their respective meal orders.

Who got the better deal?

To determine who got the better deal, we can calculate the cost per meal for both families based on the meals they purchased.

Johnsons:

  • Meals Ordered: 2 burger meals and 5 hot dog meals
  • Cost Calculation:
    • Cost of burger meals: \( 2 \times 8 = 16 \)
    • Cost of hot dog meals: \( 5 \times 6 = 30 \)
    • Total cost for the Johnsons: \( 16 + 30 = 46 \)
  • Total Meals: 2 + 5 = 7 meals

Cost per meal for the Johnsons: \[ \text{Cost per meal} = \frac{\text{Total cost}}{\text{Total meals}} = \frac{46}{7} \approx 6.57 \]

Wilsons:

  • Meals Ordered: 5 burger meals and 2 hot dog meals
  • Cost Calculation:
    • Cost of burger meals: \( 5 \times 8 = 40 \)
    • Cost of hot dog meals: \( 2 \times 6 = 12 \)
    • Total cost for the Wilsons: \( 40 + 12 = 52 \)
  • Total Meals: 5 + 2 = 7 meals

Cost per meal for the Wilsons: \[ \text{Cost per meal} = \frac{\text{Total cost}}{\text{Total meals}} = \frac{52}{7} \approx 7.43 \]

Conclusion:

  • Johnsons: Approximately $6.57 per meal
  • Wilsons: Approximately $7.43 per meal

The Johnsons got the better deal because they paid approximately $6.57 per meal, while the Wilsons paid approximately $7.43 per meal.
