Question

Company A offers a starting salary of $28000 with a raise of $3000 each year, Company B offers a starting salary of $36000 with a raise of $2000 per year. Company C offers a starting salary of $18000. After how many years would the salaries for Company A and Company B be the same? How much raise per year would Company C have to offer to equal the salaries of Company A and Company B in the year in which the salaries of those two companies are the same?

Answer 1

11 years.

Hope I helped! Good luck :)

Answer 2

We can conclude that both will intersect at a certain angle, depending on this algorithm I created.

28000 + 3000x = 36000 + 2000x

The f(x) intercept for g(x) is = 9 and -9

If you square this by light, the arithmetic of 9x+5x=21s(x)

Thus we can simply and get 11 years.
