Question: 203
9. Large ice cream cones cost twice as much as small ones. Linda bought 3 large cones and 3 small cones for $13.50. How much does a small cone cost?
- A. $0.75
- B. $1.00
- C. $1.25
- D. $1.50
Correct Answer: D
Explanation:
D is correct. Let x = cost of small cone. 2x = cost of large cone.
3 small cones + 3 large cones = $13.50
3x + 3(2x) = $13.50
3x + 6x = $13.50
9x = $13.50
x = $1.50
