Ответ:
Jose's solution is not correct, the auditorium has
rows
Step-by-step explanation:
we have
where
f(x)------> is the total number of seats in the auditorium
x----> represents the number of rows
How many rows are there in the auditorium if it has a total of 416 seats?
so
Find the value of x for f(x)=416 seats
substitute the value of f(x) in the equation
Using a graphing calculator
The values of x are
The solution is
x=16 rows because the number of rows can not be a negative number
