Answer:
The salary of that person previously was $6410.323
Step-by-step explanation:
Let the initial salary be 'x'
so, it can be written as
x + ( 15% of x) = $9,936
=> x + 15x÷100 = $9,936
=> 100x+15x÷100 = $9,936
=> 115x = $9,936 × 100
=> 115x = $9,93,600
=> x = $9,93,600÷155
∴ x = $6410.323
Stay well be happy
