Help please show work too

B

Step-by-step explanation:

I am not sure what your teacher wants but I guess you can say the following:

at n = 1, the cost is 4 dollars.

at n = 2, the cost is 8 dollars.

This trend is the same where the cost increases by 4 as n increases by 1. This means the C = 4n. We can check this by plugging values into the equation.

For the first row, C = 4, n = 1, and so the equation satisfies it. For the second row in the table, C = 8, n = 2, and so the equation works again. The other data points also agree using the equation.    

answer: a and c are correct
