Answer:
3
Step-by-step explanation:
Note that
(
)² = a, for example
(
)² = 10² = 100 ← value inside the radical
Thus
(
)² = 3
In order to determine the correct answer, it would be helpful to set up equations. We do as follows:
Let x = students
y = adults
x + y = 215
.50x + 2y = 250
SOlving simultaneously, we have:
x = 120 students
y = 95 adults
Hope this answers the question. Have a nice day.
