Asmart phone plan has a monthly base fee that includes 5 gigabytes of data. an overage charge is applied when the data usage exceed 5 gigabytes. the equation c = 59 + 15(g − 5) models the plan, where c represents the monthly cost, in dollars, and g represents the total number of gigabytes used for the month. what does the value 15 represent in the equation a: the base fee per month, in dollars, for the plan b: the cost, in dollars, for each additional gigabyte used. c: the average cost, in dollars, for data usage per month. d: the average data usage, in gigabytes, per month

B The cost, in dollars, for each additional gigabyte used.

Step-by-step explanation:

C = 59 + 15(g − 5)

when g=5, C=59 where it is the monthly cost

when g=6, c=59 +15, interpret that each additional gigabyte used will increase the cost for 15

B. The cost, in dollars, for each additional gigabyte used.

Step-by-step explanation:

We are given that,

The equation modeled for the plan is, .

Since, we have that,

The plan has a monthly charge that includes 5 gigabytes of data and over-charge fee for gigabytes exceeding 5 gigabytes.

Thus, when g= 5, C= 59, in dollars.

Also, when g> 5, .

So, we get that,

The expression represents the cost for the additional gigabytes used.

Thus, 15 represents the cost, in dollars, for the additional gigabytes used.

Thus, option B is correct.

all but the second one
