It can be computed by dq/dp X P/Q
So, derivative w.r.t to p of the function shall be 10 and then multiply with P/Q . 10 X 15/50

Q = -100+10P
P = 15, By substituting, you will get Q = 50
By applying derivation to the above equation, you will get Delta Q/ Delta P = 10.
Apply the formula of point elasticity and you get elasticity as 3

Substitute price =15 in equation
So q=-100+10(15)
q=150-100
q=50
Elasticity=q/p= 50/15=3.3
