    The cost of 25 apples is less than $9.50. The cost of 12 apples is more than 3.60. What are the possible prices of one apple?

    Let a be the price of each apple. We're given 2 inequalities:
    1. 25a < 9.50
    2. 12a > 3.60
    Typing 25a < 9.50 into our search engine, we get a < 0.38
    Typing 12a > 360 into our search engine, we get a > 0.3

    Therefore, the possible prices a of one apple are expressed as the inequality:
    0.3 < a < 0.38
