### Instruction:
Arwen and Elrond picked some flowers. Arwen was able to get 20 tulips and Elrond was able to get twice as many tulips as Arwen did. How many tulips were they able to get in total?

### Response:
 เอลรอนด์สามารถเก็บดอกทิวลิปได้ 20 x 2 = <<20*2=40>>40 ดอก
ดังนั้น จำนวนดอกทิวลิปทั้งหมดที่พวกเขาเก็บได้คือ 20 + 40 = <<20+40=60>>60 ดอก
