A customer is comparing two different text message plans at Cellular Bargains. He wants to find out which plan allows the most text messages for the same cost. The Pay Per Text Plan charges $10 per month and s0.10 for each text message. Write a function that models this plan, stating what your variables represent.

Answer: C = 10+0.10m

Step-by-step explanation:

Hi, to answer this we have to write a function with the information given:

So, the cost of the Pay Per Text Plan (C) is equal to the fixed cost per month of the plan (10), plus the product of the cost per message (0.10) and the number of messages (m)

Mathematically speaking:

C = 10+0.10m

Where:

C is the total cost of the plan

m is the number of messages

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
