Carl tells his friend logan about a new music download service. carl says that if you download x collections per month, your monthly cost will be 2(x + 10). logan says the cost will be 2(x + 5). who is correct? a. only carl is correct. b. only logan is correct. c. both carl and logan are correct. d. both carl and logan are incorrect

The expression that gives the total monthly cost can be derived from the

sum of the monthly fee and the download fee.

The most common probable charges for a service such as a music

download service is a flat fee each month and a fee for each download.

Let y represent the flat fee, and x represent the fee per download.

If the fee per download is $2, we have;

Monthly cost, C = 2·x + y

When the monthly fee, y = 10, we have;

C = 2·x + 10

Whereby the monthly cost is y = 5, we have;

C = 2·x + 5

Therefore, the coefficient of x which is the cost per download is used to multiply x only rather than (x + 10) or (x + 5)

Therefore; Both Carl and Logan are incorrect
