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?

c = 8 + 0.03m

Step-by-step 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

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
