Jake is traveling to visit a friend. He is trying to pack his bag. The airline he is flying has a baggage weight policy, stating that each bag must weigh less than 50 pounds. Jake determines that one outfit weighs two pounds and one pair of shoes weighs three pounds.

Which of the following graphs represents the number of outfits and shoes that Jake can pack and still follow the baggage weight policy?

J.
K.

L.

To solve this problem, we need to establish a relationship between the number of outfits (let's denote it as \( x \)) and the number of pairs of shoes (let's denote it as \( y \)) that Jake can pack without exceeding the 50-pound weight limit.

Given:

  • Each outfit weighs 2 pounds: \( 2x \)
  • Each pair of shoes weighs 3 pounds: \( 3y \)
  • The total weight must be less than 50 pounds: \( 2x + 3y < 50 \)

This inequality can be rearranged to help visualize it in a graph:

  1. Rearranging the Inequality: \[ 3y < 50 - 2x \] \[ y < \frac{50 - 2x}{3} \]

This represents a linear equation and can be graphed as follows:

  1. Finding Intercepts:
    • To find the y-intercept (when \( x = 0 \)): \[ y < \frac{50 - 2(0)}{3} = \frac{50}{3} \approx 16.67 \]
    • To find the x-intercept (when \( y = 0 \)): \[ 0 < \frac{50 - 2x}{3} \implies 50 - 2x > 0 \implies x < 25 \]

So the line \( y = \frac{50 - 2x}{3} \) will intercept the axes at approximately \( (25, 0) \) and \( (0, 16.67) \).

  1. Graphing the Region: The solution region is below the line \( y = \frac{50 - 2x}{3} \) and above the coordinate axes \( x \geq 0 \), \( y \geq 0 \).

Now, you'll need to compare this to the provided graphs (J, K, and L) to find the one that accurately depicts this area of viable outfits and shoes within the constraints.

Since I don't have the visuals for graphs J, K, and L, review each one to identify which shows a shaded area below the line \( y = \frac{50 - 2x}{3} \) in the first quadrant (the area where both \( x \) and \( y \) are positive).

If you can provide details about each graph, I can help you identify which one accurately represents Jake's packing limitations based on the baggage policy.
