You can put this solution on YOUR website! Maria paints portraits that she sells for $30 each.
Her cost, C, is C= 160+16n, where n = number of portraits sold.
Write an inequality to represent the number of portraits she needs to sell to earn a profit of at least $300
:
Revenue; r = 30n
cost; c = 160 + 16n
r - c = profit; therefore
:
30n - (160+16n) => 300
30n - 160 - 16n => 300
30n - 16n = 300 + 160
14n => 460
n =>
n => 33 portraits to make at least $300

Check this
30(33) = $990 revenue
160 + 16(33) = $688 cost
-----------------------
profit: $302
:
You can check this with 32 portraits and see it will be less than $300 profit
