Price elasticity is defined as 
.
Here, the question has omitted to define variables, so we will ASSUME
p=price
x=variable,
and we're given
p+x^2-160=0
We calculate
by implicit differentiation with respect to p:
1+2x (dx/dp)=0
=>
E(x)=(dx/dp)=-1/(2x)
Therefore the price elasticity at x=65 is
E(65)=1/(2*65) =-1/130 (approximately -0.00769)

Answer:
Option d.
Step-by-step explanation:
It is given that Aarav has 3,250 followers on social media. His number of followers is increasing at a rate of 3% per week.
Initial followers = 3,250
Rate =
The exponential growth function is
where, a is initial value, r is rate and w is time per week.
Substitute a=3,250 and r=0.03.
Therefore, the correct option is d.
