Step-by-step explanation:
We know that he DOES spend $680, so we can put (680 = )
40 per month would be 40 times how many months total. Since we don't know how many months, we can use (40m)
3 months free simply means that he doesn't have to pay that price so we can take 3 months out of his total (- 3)
