Awebsite-hosting service charges businesses a onetime setup fee of $275 plus d dollars for each month. if a business owner paid $1,091 for the first 12 months, including the setup fee, what is the value of d? a. create an equation to represent this situation. b.solve your equation above to find the value of d. show all work to receive full credit

(a) The total amount that is to be paid by the company is equal to the setup fee and the total fee collected for each month. The equation that can be used in order to determine the answer is,
      S = 275 + dx

where S is the total amount paid, d is the monthly fee and x is the number of months. Substituting the known values from the given,
    1091 = 275 + d(12)

or,   1091 = 12d + 275

(b) To determine the value of d, follow the steps given below,
    Substract 275 in each side of the equation,
    1091 - 275 = 12d + 275 - 275

Simplifying,
     816 = 12d 

    Divide both sides of the equation by 12,
      816/12 = 12d/12

Simplifying,
   68 = d
  
  or d = 68

Hence, d = 68
