Case study. Calculations for profit, loss, understanding costs and demand curve. For example: Evaluating a new credit card product aimed at young professionals aged 25–35. The card offers 2% cashback on all purchases, no annual fee, and a sign-up bonus of $200 after spending $1,000 in the first 3 months. You’ve been asked to assess whether this product is financially viable and how it compares to existing offerings. Your manager wants a recommendation on whether to launch, modify, or shelve the product.
