is that correct and why, please help solve

Question 33 (1 point) J Saved Suppose two rms compete by choosing advertising levels A1 and A2 . The prot functions of each rm are given by: 10141 + aAlAZA% 10142 + aAlAz-Ag \"1 (141,142) 1120411142) where a is a constant. These prot functions include the costs of advertising. Firms choose advertising levels simultaneously and once-and-forall. Suppose a = -1, at the Nash equilibrium, rm 1 will set A1= 15/ .(Keep 2 decimal places)
