Answer 1

The solution code is written in C++

1. float cellPhone(int m, int tx){
2. float COST_PER_MIN = 0.1;
3. float COST_PER_MESSAGE = 0.2;
5. float bill_amount = m * COST_PER_MIN + tx * COST_PER_MESSAGE;
7. return bill_amount;
8. }

Step-by-step explanation:

Firstly, declare a function named cellPhone() that takes two input parameters, m and tx (Line 1).

Since the policy of the carrier company is not given in the question, I make a presumption that the cost per minutes is $0.10 and the cost per message is $0.20 (Line 2- 3).

Next, apply the formula m * COST_PER_MIN + tx * COST_PER_MESSAGE to calculate the total bill (Line 5) and return the bill_amount as function output (Line 7).
