Answer 1

The answer is D

Explanation:

Total # of student going field trip = 50 students

From the question, we know that they are planning to use two methods of traveling: car and van.

We also know that x represents the number of cars used and y represents the number of vans used.

We also know that cars can hold 5 students each and vans can hold 7 students each.

So the equation will be 5x+7y = 50. The answer is D.
