    Dave has $11 and he buys a book for $8 but he spends an equal amount of money on 2 cards. Let’s model this problem with an inequality.

    x = $ spent on one card.

    2x + $8 ≤ $11

    Let’s subtract $8 from both sides.

    2x ≤ $3

    Divide both sides by 2

    x ≤ $1.5

    Dave can spend at most $1.5 on each card.
