Given the exponential function a(x) = p(1 + r)x, what value for r will make the function a decay function?

r = 2.1
r = −0.1
r = 0
r = 0.1

Any negative value of r will make the sum 1+r be less than 1.

The appropriate choice is r = -0.1.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
