Question

A florist buys roses at $18 per dozen. If she sells them at $ 1.20 each, express her lost as a percentage of her selling price.

Answer 1

Answer:

cost of each rose =18/12 = $ 1.50

selling price of each rose = $ 1.20

so, loss = 1.50-1.20 = $ 0.30

so, loss percent = loss *100/cost price

=0.30*100/1.50 =20% answer

Answer 2

Answer: 25%

Step-by-step explanation:

S.P. of 12 roses = $1.20 * 12

                          = $14.40

Loss Percentage = $18-$14.40/$14.40 *100%

                             = $3.6/$14.4*100%

                             = 25%
