<PRE><B>Question 990870</B>
60000 = 500p - p^2
p^2 - 500p + 60000 = 0
(p - 200) * (p - 300) = 0
p is 200 or 300
We are asked for the fewest number of paintings the artist can sell to make a profit of at least $60,000, therefore
the answer is 200 paintings
*******************************************
check the answer
60000 = 500(200) - 200^2
60000 = 100000 - 40000
60000 = 60000
our answer checks
