To find the value of \( c \) using the equation \( c = 11 - p \) and knowing that \( p = 4 \), you can substitute 4 for \( p \):
\[ c = 11 - p \] \[ c = 11 - 4 \] \[ c = 7 \]
So the value of \( c \) is \( 7 \).
we know that p = 4 is part of the solution. Use the second equation to find the value of c.
3c+2.5p = 31
c = 11−p
p = 4
c = 11−p
c =
