Question 776305: A person starts his job with a certain monthly salary and earns a fixed increment every year. If his salary was Rs 4500 after 4 years of service and Rs 5400 after 10 years of service, find his initial salary and the annual increment. I can't figure out if I have to take into account the 12 months in a year into the equation. Thankyou in advance. Appreciate the time and effort. Answer by solver91311(24713) (Show Source):
No, you don't need to take the "12 months per year" into account. You have two data points: (4, 4500) and (10, 5400). Since the problem implies a fixed annual increase, the function must be linear.
Use the two-point form of an equation of a line:
where and are the coordinates of the given points.
Simplify and put the equation into slope-intercept form,
Then will be the initial monthly salary and will be the annual increment.
