## Mathematics: Standard Multiple Choice

A florist buys roses at $0.50 apiece and sells them for$1.00 apiece. If there are no other expenses, how many roses must be sold in order to make a profit of $300? First, note the bottom line. p =$300, r = ?

Assess your options. You know how much the roses cost and how much they sell for, so you could calculate the amount of profit earned with each flower. You could also translate the problem into a formula to determine how many flowers will yield $300 in profit. The first solution is more efficient, so begin by finding the amount of profit each flower brings in. Since they cost fifty cents and sell for a dollar, each flower earns fifty cents in profit.$1.00 - $0.50 =$0.50

Next, how many flowers are needed to add up to $300 total? .5r = 300 $r=\frac{300}{.5}$ r = 600 Loop back to the bottom line to check whether you answered the question correctly. You were looking for the number of roses that would yield$300 in profit. Since that is what you found, look at the answer choices to see which one matches.

A) 100

B) 150

C) 200

D) 300
