Mason painting services has a weekly payroll of $28,000. december 31 falls on wednesday and mason will pay its employees the following monday (january 5) for the previous full week. assume that mason has a five-day workweek and has an unadjusted balance in salaries expense of $800,000 at december 31. what amount should be debited to salaries expense on december 31?

28000 / 5 days = $5,600 per day

Wednesday, Thursday, Friday = 3 days.

5,600 x 3 days = $16,800

The amount should be $16,800

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
