Dish Network charges $100 for installation plus $55 each month for their service. If you have spent a total of $540, how many months have you had Dish Network?

Answers

Answer:

8 months

Step-by-step explanation:

cost = 100 + 55m where m is the number of months

540 = 100 + 55m

Subtract 100 from each side

540-100 = 100 + 55m -100

440 = 55m

Divide each side by 55

440/55= 55m/55

8 = m

8 months

Answer:

Step-by-step explanation:

55m + 100 = 540

55m = 440

m = 8 months
