Tyler trades in a car worth $5,000 (wholesale) on a new $15,000 car, but still owes $7,000 on his old car. How much will he owe
Marina86 [1]

Answer: He owes $17,000 on his new car.


Explanation: Because Tyler traded his car which was worth $5,000 on a $15,000 car this would decrease the cost by $5,000 due to the car he traded in, but since he still owed $7,000 on the car that he traded in he will still have to pay that off, which was grouped into the bill of the new car that he bought.

lidiya [134]

Answer:

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;
  4.    
  5.    float bill_amount = m * COST_PER_MIN + tx * COST_PER_MESSAGE;
  6.    
  7.    return bill_amount;
  8. }

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).
