Final answer:
The cost of both providers will be the same after 7 months, and the cost will be $616.
Step-by-step explanation:
To find the number of months in which both providers will cost the same, we need to set up and solve the equation:
70 + 82t = 175 + 67t
First, we combine like terms:
82t - 67t = 175 - 70
15t = 105
Next, we divide both sides of the equation by 15 to solve for t:
t = 7
Therefore, both providers will cost the same after 7 months. To find the cost, we substitute the value of t into either of the original equations:
C = 70 + 82t
C = 70 + 82(7)
C = 616
So, both providers will cost $616 after 7 months.
