Answer:
250 adults
Step-by-step explanation:
With the information of the problem we have a system of two linear equations:
Where x represent the quantity of adults and y represent the student. Solving the first equation for x we have:
Using this result in the second equation:
With this result we know that we have 500 students, using the result of y in the first equation we will find the answer for x then:
Then the we have 250 adults.
