Question

Family budget: Income $3,000. Rent $1,200, Food $400, Utilities $200, Fun $150.  Formula for leftover money after expenses.

GPT-5 mini · Answer

Let I = income, R = rent, F = food, U = utilities, N = fun (or any other expense).  
Formula: Leftover L = I − (R + F + U + N).

With your numbers: L = 3000 − (1200 + 400 + 200 + 150) = 3000 − 1950 = $1,050.
