You've had a lot of answers this morning. Now it's your turn. How do YOU think you should solve this problem?
C+ p=60
4.00c+2.50p=3.00*60
But how after that
4.00c+2.50p=3.00*60
But how after that
Taylor, we have done this many times now
from the first line, p = 60 - c
use that (60-c) for p in the second line
from the first line, p = 60 - c
use that (60-c) for p in the second line
