The salary of Jim is expressed in algebra as 1.07S ( if the initial salary S is increased by 0.7) // shouldn’t it be S+ (S - 0.7S)

Does someone understand where that number comes from?

Posted from my mobile device

Let Initial salary = 100
Salary Increased by 7%
So, increased salary = 100*7/100= 7
Final salary = initial+increase =100+7=107

If you are not able to solve the question with algebra, try to solve it using numbers.
