What type of problem-solving is the customer using? A customer is making a purchase decision between several prepackaged meals by looking at the nutrition information labeling to determine which has the least amount of sodium per serving.

Extended problem-solving is characterized by a more in-depth decision-making process involving significant research and consideration, often seen in high-involvement purchases. In this case, the customer is not delving into extensive evaluations or comparisons; they are simply looking at sodium levels, indicating a less complex decision-making approach.

Routine problem-solving refers to low-involvement decisions made with minimal thought, such as purchasing everyday items without much consideration. This situation does not fit routine problem-solving since the customer is actively evaluating nutritional information, which requires more thought than typical routine purchases.

Impulse buying occurs when a consumer makes a spontaneous purchase without prior planning or consideration. Here, the customer is deliberately assessing sodium content before deciding, which is the opposite of impulsive behavior, making this option incorrect in this context.
