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

Respuesta :

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

sum of the monthly fee and the download fee.

Correct option:

  • C; Both Carl and Logan are incorrect

Reasons that make option C correct:

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.

Formula for the total monthly cost of the music download service:

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
