    1)

    Ms. Sung is not able to spend more than 320 per month.

    The best inequality for this would be

    320 – 4x ≥ 0

    Where x is the amount she spends per shopping trip

    2)

    x = 5 so let’s plug in 5 for x

    It seems as if your inequalities glitched so I’m unable to help you directly.

    a.
    -2(5) (something) 12
    -10 (something) 12

    If it’s the less than symbol, then it is true
    If it is the greater than symbol, then it is false
    If it’s the less than or equal to symbol, it is true
    If it’s the greater or equal to than symbol, then it is false

    b.

    (5) – 2 (something) 7
    3 (something) 7

    If it’s the less than symbol, then it is true
    If it is the greater than symbol, then it is false
    If it’s the less than or equal to symbol, it is true
    If it’s the greater or equal to than symbol, then it is false

    c.

    2(5) (something) 12
    10 (something) 12

    If it’s the less than symbol, then it is true
    If it is the greater than symbol, then it is false
    If it’s the less than or equal to symbol, it is true
    If it’s the greater or equal to than symbol, then it is false

    d.

    (5) – 7 (something) 2
    -2 (something) 2

    If it’s the less than symbol, then it is true
    If it is the greater than symbol, then it is false
    If it’s the less than or equal to symbol, it is true
    If it’s the greater or equal to than symbol, then it is false

    3)

    -4x = 42
    Divide by -4

    x = -10.5
