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
