Answer to a math question There are 120 seats in the cinema. Eighth grades come with the same number of students. If three grades come, there will be 54 free seats left. How many seats will be left if four grades come?
1. Izračunaj broja mjesta zauzetih za 3 razreda: 3x
2. Postavi jednadžbu: 120 - 3x = 54
3. Izračunaj broj učenika u jednom razredu: 3x = 66 x = \frac{66}{3} = 22
4. Izračunaj broj mjesta zauzetih za 4 razreda: 4x = 4 \times 22 = 88
5. Izračunaj broj slobodnih mjesta za 4 razreda: 120 - 88 = 32
Odgovor: Broj učenika u jednom razredu je 22, a broj slobodnih mjesta kada dođe 4 razreda je 32.
