**Damon**, Wednesday, February 18, 2009 at 2:56pmC is in hundred so divide by 100

substitute in C = 5250 and solve for x

substitute in C = 7810 and solve for x

**Randy**, Wednesday, February 18, 2009 at 3:11pmC(x) =16x+130 {x| 320 < x <480

525,000/100

5,250=16x+130

16x=5,250-130

16x=5,120

x=5,120/16

x=320

781,000/100

7,810=16x+130

16x=7,810-130

16x=7,680

x=7,680/16

x=480

Then if that is true then this is the solution? I think I got it!
