2. Jose earns a base salary of $2000 per month. Once he reaches $42000 in total sales, he earns an additional 5% commission (salary) on the amount of sales over $42000. Let s be the amount of his total sales for the month and G(s) be the amount of his salary for the month.

a. [5 pts] Graph G(s) for s values between $0 and $100000 in sales. Indicate your scale on both the horizontal and vertical axes, and be sure to label what quantities (salary or sales) each axis represents.

b. [2 pt] If Jose had $76000 in sales, how much was his salary for that month?

c. [2 pts] If Jose's total salary for a month was $4100, how much were his total sales for that month?

d. [2 pts] Compute G(25000) and interpret what this means in the context of the problem (in terms of the monthly salary and the sales).
