Step-by-step explanation :

Let the anytime minutes be, x and text messages be, y.

As we are given that a month he used 200 anytime minutes and 400 text messages, and paid $80.00. The equation will be:

        ...........(1)

    ............(A)

And,

As we are given that a month he used 150 anytime minutes and 350 text messages, and paid $67.50. The equation will be:

        ...........(2)

Now solving these two equation by substitution method by putting equation A in equation 2, we get:

As we know that, $ 1 = 100 cents

So, $ 0.15 = 15 cents

y = 15 cents

Now put the value of 'y' in equation A, we get:

x = 10 cents

As per given statements we conclude that, Each text message costs 5 cents more than each anytime minute is the correct statements.
