    answer:

    30 > 4x + 2 and 6 books

    step-by-step explanation:

    • read the question and set up the inequality
    • let x = number of books he can afford

    30 > 4x + 2

    • 30 would be on one side since that’s the most he can spend
    • 4x because each book is $4
    • + 2 because there is a charge of $2

    30 > 4x + 2

    28 > 4x

    7 > x

    • he can afford 6 books
    • it cannot be 7 because if he does buy 7 books, it would cost more than $30
