See the solutions below
Step-by-step explanation:
Initial Salary= $925
Final salary= $1036
% increase= Change/initial *100
substitute
% increase= 1036-925/925 *100
% increase=111/925 *100
% increase=0.12 *100
% increase=12%
2. Let us find 16% of $925
=16/100*925
=0.16*925
=$148
Hence the salary would have been
=148+925
=$1073
