Honestly I would recommend you watch an online video on it.
But think of it this way,
Combinations is used when you "Choose" a certain number of things out of a total number and order does not matter.
Permutations are when you permutate or arrange in a "Particular" order where order matters.
Answer:
25 months
Step-by-step explanation:
Plan A : $70 per month
Plan B : $50 per month + $500 as a one time cost.
So for A $70 a month would take 8 months to be at least $500
And for B it in those 8 months it would cost you $900
But we have to keep going up until they are equal
25*70 = 1750
(25*50) = 1250+500=1750
So yes 25 months is correct
No it doesn’t have horizontal asymptote
