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.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
