Answer: Choice A) 75p + 35d - 150
===================================================
Work Shown:
p = number of paintings sold
75p = amount made from paintings alone ($75 per painting)
d = number of drawings sold
35d = amount made from drawings only ($35 per drawing)
R = revenue = amount of money coming in
R = 75p+35d
C = cost = amount of money going out
C = 150
P = profit
P = R - C
P = ( R ) - ( C )
P = ( 75p+35d ) - ( 150 )
P = 75p + 35d - 150
