A theater sold 13 tickets for a total of 345 euros. Adult tickets cost 45 euros and child tickets cost 15 euros. How many adult tickets were sold?
Answer and explanation
Correct answer: B. 5
- Step 1: Let a be the adult tickets: a + c = 13 and 45a + 15c = 345.
- Step 2: Substituting c = 13 - a gives 30a = 150, so a = 5.
Answer
5.
Why not the others: 8 is the number of child tickets; the other values fail to match the total takings.
