    Kate spent at most $2.50 on apples and oranges. She bought 5 apples at $0.36 each. What is the most She spent on oranges

    Assumptions and givens:
    • Let a be the total cost of apples
    • Let o be the total cost of oranges

    The phrase at most means less than or equal to, so we have:
    a + o <= 2.50

    Find the cost of apples (a)
    a = price per apple * quantity of apples
    a = 0.36 * 5
    a = 1.8

    Our new inequality with a = 1.8 is:
    1.8 + o <= 2.50

    Typing this inequality into our search engine, we get:
    o <= 0.7
