You can put this solution on YOUR website! Let X be the number of dozen he bought.
Then (X-5) is the number of dozen he sold.
He bought 56 dozen and sold 51 of them.
That's a lot of flowers and not a lot of profit :(
You can put this solution on YOUR website! 1.50x=2(x-5)-18
1.50x=2x-10-18
1.5x-2x=-28
-.5x=-28
x=-28/-.5
x=56 dozen roses were bought.
Proof:
1.50*56=2(56-5)-18
84=2*51-18
84=102-18
84=84
