AlgebraEasyEquation for a total number of wheels
Algebra practice question
A yard holds c cars with 4 wheels each and t tricycles with 3 wheels each, and there are 50 wheels in all. Which equation represents this?
- A. 4c + 3t = 50Correct
- B. 3c + 4t = 50
- C. c + t = 50
- D. 7(c + t) = 50
Answer: A. 4c + 3t = 50
4 wheels per car and 3 per tricycle.
Why the other answers are wrong
- B. 3c + 4t = 50
- This swaps the wheel counts.
- C. c + t = 50
- This counts vehicles, not wheels.
- D. 7(c + t) = 50
- This gives every vehicle 7 wheels.
