A theater sold 9 tickets for a total of 275 shekels. Adult tickets cost 50 shekels and child tickets cost 25 shekels. How many adult tickets were sold?
Answer and explanation
Correct answer: B. 2
- Step 1: Let a be the adult tickets: a + c = 9 and 50a + 25c = 275.
- Step 2: Substituting c = 9 - a gives 25a = 50, so a = 2.
Answer
2.
Why not the others: 7 is the number of child tickets; the other values fail to match the total takings.
