Solution
The correct option is D$50 The price of a dozen tulips is $30.
Number of tulips in a dozen =12
Price of 12 tulips is $30.
Price of one tulip = Price of 12 tulips ÷ Number of tulips =30÷1230÷12=2.5
Price of each tulip =$2.5
Price of 20 tulips = Number of tulips × Price of each tulip =20×$2.5 20×$2.5=50.0=$50
So, the price of 20 tulips is $50.
Hence, option C is correct.
