What is the ANWSER to the question ? Thank you

Answer 1

Each salary pattern can be described with an expression that looks like:

starting salary + (annual increase) x (number of years)

Company A:
`24000+3000n`
Company B:
`30000+2400n`

You want to know when those two expressions will be equal.


`2400+3000n=30000+2400n \\ 24000+600n=30000 \\ 600n=6000 \\ n=10`

The salaries from Company A and Company B will be equal after 10 years.
