I already know the answers for the first two, however I need help with the other ones. I added the first two questions because they are related to the other questions.

Ayana is considering two job offers. Job A promises her a starting salary of $40,000 with a $1000 annual raise. Job B promises a starting salary of $30,000 with a 5% annual raise. 1 Construct a model to represent the salary offers for Job A and Job B. Be sure to define your variables. SEP+rt S: Salary P: Initial Salary r. annual rate t: time Job A: S = 40000 + 1000 *t S = P(1+r)^t S: Salary P: Initial Salary rannual rate t: time Job B: S = 30000(1+0.05)^t 2 Which kind of model does each job represent? Find the average rate of change of the salary for both Job A and Job B over 20 years. Job A: Simple Interest Job B: Compound Interest The average rate of change of Job A is constant. The average rate of change for Job B is = (y2-y1)/(x2-x1) (30000 - 79598.9)/(0-20) = 2479.945 4 After how many years will the annual salary for Job A exceed the annual salary for Job B? Explain your reasoning. Validate your solution to assess the reasonableness of your model. Write and evaluate a series to project Ayana's total earnings to the nearest dollar if she stays at Job B for 20 years. Validate your solution to assess the reasonableness of your model.
