Final answer:
Pack A has cheaper cookies than Pack B.
Step-by-step explanation:
To determine which pack of cookies is cheaper, we need to compare the price per cookie for each pack. For Pack A, the price per cookie is calculated by dividing the total cost ($5.90) by the number of cookies (36), which gives us $0.163 per cookie. For Pack B, the price per cookie is calculated by dividing the total cost ($4.10) by the number of cookies (24), which gives us $0.171 per cookie. Therefore, Pack A has cheaper cookies than Pack B.
