Could someone help me with this question? I am in a hurry. Thank you so much I will upvote

Two mortgage options are available: a 15-year fixed-rate loan at 4.8% with no discount points, and a 15-year fixed-rate loan at 4.5% with one discount point. How long do you have to stay in the house for the mortgage with points to be a better option (rounding to 2 decimal places)? Assume a $100,000 mortgage.
