Final answer:
The question seeks the percentage increase of WellCare's products from 2023 to 2024, which requires original and new product counts to calculate. The provided information is insufficient to determine the correct answer from the given options.
Step-by-step explanation:
The question asks for the percentage increase of WellCare's product expansion from 2023 to 2024. To calculate the percentage increase, one would need to know the original number of products in 2023 and the expanded number of products in 2024. The formula to calculate the percentage increase is:
(New Amount - Original Amount) / Original Amount × 100%
You would subtract the Original Amount from the New Amount to find the difference. Then, you divide the difference by the Original Amount. Lastly, you multiply by 100% to convert it into a percentage. Without the actual numbers of products, we cannot provide an accurate answer to this question. Thus, we are unable to determine whether the correct answer is a) 10%, b) 15%, c) 20%, or d) 25% based solely on the information provided.
