Step-by-step explanation:
You solve the equation
Answer:
y= 250( 1-0.21)^x
Step-by-step explanation:
This represents exponential decay
32*x < 720-120
32*x < 600
x < 18.75
because of x represents the number of seats in each row, it has to be a natural number -- whole. so x=18 is the max number of seats in each row and x < 18.75 is the desired inequality.
