    Sal paid 4 cents per text.

    Step-by-step explanation:

    Given,

    Total amount paid = $28

    Total texts sent = 386

    Fixed fee = $ 14.25

    Let,

    x be the cost per text

    y be the total amount paid

    y = 386x + 14.25

    28=386x+14.25\\28-14.25=386x\\13.75=386x\\386x=13.75

    Dividing both sides by 386

    \frac{386x}{386}=\frac{13.75}{386}\\x=0.36

    Cost per text = $0.036 = 0.04*100 = 04 cents

    Sal paid 4 cents per text.
