Question

The charge for an international long-distance telephone call with JC Phone Service is $2.20 for the connection plus an additional $0.14 per minute. Write an equation that shows the relationship between the total charge (c) and the number of minutes (m) for an international call.

A) c = 0.14m - 2.20.
B) c = 0.14m + 2.20.
C) c = 2.20m + 0.14.
D) c = 2.20 + 0.14m.

Answer 1

The correct equation that represents the total charge for an international call with JC Phone Service as a function of minutes is B) c = 0.14m + 2.20.

Step-by-step explanation:

The relationship between the total charge (c) for an international call and the number of minutes (m) with JC Phone Service can be represented by a linear equation.

The initial charge is a flat fee, which is followed by an additional per-minute charge. Since the charge includes a $2.20 connection fee plus $0.14 for each minute of the call, the equation will start with the connection fee and then add the per-minute rate multiplied by the number of minutes.

The correct equation is thus option B) c = 0.14m + 2.20, where c is the total charge in dollars and m is the number of minutes.

The equation that shows the relationship between the total charge (c) and the number of minutes (m) for an international call is c = 2.20 + 0.14m. The initial charge of $2.20 is added to the product of $0.14 per minute and the number of minutes.
