A florist buys roses at 0.50 dollar a piece and sells them for 1.00 dollar a piece. If there are no other expenses, how many roses must be sold in order to make a profit of 300 dollars?
 
(A) 100
 
(B) 150
 
(C) 200
 
(D) 300
 
(E) 600


正确答案：

The correct answer is E
 
Explanation
 
Each rose brings a profit of 1.00 dollar minus 0.50 dollar, or 0.50 dollar. The number of roses that need to be sold to make a profit of 300 dollars is 300 dollars divided by 0.50 dollar. This is 600 roses.
