Question 987504: A company produces alarm clocks. During the regular workweek, the labor cost to produce one clock is $2.00. However, if a clock produced on overtime, the labor cost to produce it is $3.00. Management has decided to spend no more than $21,000 on labor costs per week. The company must produce 10,000 clocks this week. What is the minimum number of clocks that must be produced during the workweek?
I hope you guys can help me solve a word problem! I've tried to figure out the different equations for the workweek vs. overtime and the 10,000 is the number I think that's throwing me off the most! Hope you can help! Thank you!

Question 992342: Determine the values of the variable for which the expression is defined as a real number. (Enter your answer using interval notation.)
square root of x^2 − 16
I squared the entire thing, so that took care of the square root. Then I factored it into (x-4) (x+4) but thats as far as I got...
help, please? :(
