Answer: 9
Step-by-step explanation:
![\frac{1}{4} (c^{3}+d^{2})](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%28c%5E%7B3%7D%2Bd%5E%7B2%7D%29)
Substitute in the values into the expression:
![\frac{1}{4} ((-4)^{3}+10^{2})\\\\=\frac{1}{4}(-64+100)\\\\=\frac{1}{4}(36)\\\\=\frac{36}{4} =9](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%28%28-4%29%5E%7B3%7D%2B10%5E%7B2%7D%29%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B4%7D%28-64%2B100%29%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B4%7D%2836%29%5C%5C%5C%5C%3D%5Cfrac%7B36%7D%7B4%7D%20%3D9)
Answer:
i think it is f(x)= 10m+0.10s
x= number text messages send
m= months
for example: if you send 200 messages and were in the plan for 3 month the function will go like this;
f(x)= 10(3)+0.10(200)
=30+20
= $50
