after how may years would Janie ^s salary be the same with both company?

Question

Janine has job offers at two company. one offer staring salary of $28000 with a rise of $3000. the other company offer starting salary at $36000 with a raise of $2000. after how may years would Janie 's salary be the same with both company?

Answer 1

Are we to assume the raises are annual??

If so:

 

Let x = # years working the job

The salary for job 1 would be $28000 + 3000x

The salary for job 2 would be $36000 + 2000x

We need to know when the salaries would be equal so

set the equations equal to each other and solve for x.

 

28000 + 3000x = 36000 + 2000x

Subtract 2000x from each side

28000 + 1000x = 36000

Subtract 28000 from each side

1000x = 8000

Divide both sides by 1000 to isolate x

x = 8

 

The salaries would be equal after 8 years
