Let f be the purchase price for a single flower and n be the number of flowers sold.
Profit = f 1.4 n

For a $500 profit:
   500 = 0.5 1.4 n
   500 =  0.7 n
       n = 714.286 or 715 flowers

wait i don't understand explain to me how to set up the equation

anonymous · Answer

The sale price is to be set to 100% of the cost of one flower plus the profit on one flower which is 40% of the cost. 100% + 40% = 140% = 1.4

1.4 times the purchase price of one flower, times the number of flowers to be sold must equal $500.

1.4 x 0.50 x n = 500
Solve the above for n, the number of flowers to be sold to achieve a $500 dollar profit.
One cannot sell 0.286 of a flower so one has to round up to the next highest integer to determine the number of flowers to purchase in order to obtain a $500 profit.
