So here is the answer. The rent of the movie from redbox is $1.29 each night, and there is an additional fee of $0.50. So in order for us to know how much it would cost for 3 nights, we are going it to put this way. N = 0.50 + 3(1.29). And this would give us the answer of $4.37. This is the cost for 3 nights only. For 10 nights, it would be N = 0.50 + 10(1.29) and it would be $13.4. Hope this helps.
