Question 551248
The rental fee is 120
The profit for each picture frame sold is $6 (11 minus 5)
So his profit is 6*p (the number sold minus 120
The words at least is telling me greater than or equal to 
{{{6p-120>=275}}}
now we can just solve this inequality for p


{{{6p>=395}}} 
{{{p>=65.822}}}
So he needs to sell at least 66 pictures
