Answer:
C = -N(P - R)
Step-by-step explanation:
Rearrange the equation so that it is equal to C.
P = R - C/N
P - R = -C/N
-N(P - R) = C
C = -N(P - R)
Use area formula (length x width)
42 x 25.5 = 1,071
Divide by total cost of wall paper
1,071/771.25 = $1.38 per square foot
Expenditures are negatives do I'd use -42.50
