Answer:
The person will have P-4 paintings left
Explanation:
We are told that the total number of painters who entered into the painting donation agreement to the local museum is 12 painters
and they all agreed to donate 48 paintings equally
so each painter will donate
48/12= 4paintings
Since this person already had P paintings in his art collection
his painting will reduce by the 4 paintings he denoted to the local museum\
hence he will have
P-4 paintings remaining
