The answer is the red one. The green shirt is richer because when she goes out to eat at a restaurant, she only buys fruit for the refrigerator, while the woman in the red shirt has to buy food to take home to eat to save money.

"The answer is the woman in the red shirt. The woman in the green shirt appears wealthier because when she goes to a restaurant, she only buys fruit for her refrigerator, implying she has the means to eat out regularly. In contrast, the woman in the red shirt takes food home to eat, indicating she may be saving money and is more budget-conscious."
