Accepted Solution

A:
Hello! To solve this equation, let's set it up like this: 75 + 20m = 35m. This is because Company B does not charge an upfront fee, so all you have to do is 35m and Company A charges $75 upfront and then $20 per month, so you do 75 + 20m. First, you subtract 20m from both sides. When you do, you get 75 = 15m. Now, you divide each side by 15 to isolate the m. When you do that, you get 5. Let's plug in the numbers to see what we get. 20 * 5 is 100 + 75 = 175. 35 * 5 =175. 175 = 175. There. The two companies will charge the same amount in 5 months. m = 5.
