Answer:
29,800
Step-by-step explanation:
that will be 149 x 2 which equals 298
149
  ×2         Multiply 9 × 2 = 18 
------        Keep the 8 carry the 1 multiply 4 by 2 then add 1 finally multiply 2 by 1
 298
Then add two zeros at the end since we're multiplying a number with two zeros. (This method only works for numbers that end with zeros)
Final answer: 29800
