Answer 1

Answer:

C. 244

Step-by-step explanation:

It costs 79 dollars a month = 79x

It costs 0.15 dollars for every text message over 1000 = 0.15y

The equation is:

79x + 0.15y = z

X = months

Y =  Each text message over 1000

Z = the total amount spent

Let's plug in our values

79(1) + 0.15(1100) = z

79 * 1 = 79

0.15 * 1100 = 165

79 + 165 = z

79 + 165 = 244

z = 244
