A theater sold 8 tickets for a total of 165 euros. Adult tickets cost 30 euros and child tickets cost 15 euros. How many adult tickets were sold?
Answer and explanation
Correct answer: C. 3
- Step 1: Let a be the adult tickets: a + c = 8 and 30a + 15c = 165.
- Step 2: Substituting c = 8 - a gives 15a = 45, so a = 3.
Answer
3.
Why not the others: 5 is the number of child tickets; the other values fail to match the total takings.
