I need to get two equations out of this and use the substitution or elimination method to solve this problem.

**PsyDAG**, Tuesday, July 29, 2008 at 1:14amLet C = 450 - H

$1.25 (30H + 25C) = $20

Substitute the value of C in the first equation into the second. Solve for H. Put value of H into the first equation to solve for C. Check by putting both values into the second equation.

I'll let you do the calculations. I hope this helps. Thanks for asking.
