Question

Another company charges $8 per month and $0.03 per minute used. Which equation below best respresents the total cost for the month, c, for m miuntes used?

Answer 1

Answer: c = 8 + 0.03m

Explanation:

From the question, we are informed that a company charges $8 per month and $0.03 per minute used.

The equation that best respresents the total cost for the month, c, for m miuntes used will be:

c = 8 + (0.03 × m)

c = 8 + (0.03m)

c = 8 + 0.03m

For example if 10 minutes was used, the cost will be:

c = 8 + 0.03m

c = 8 + (0.03 × 10)

c = 8 + 0.3

c = $8.3
