John had 28 color pencils. He was given a new set of colour pencils which contained twice as much he already had. Jonh gave 11 coloured pencils to each of his 3 sisters. How many colored pencils did he have now ?

Answer:23Step-by-step explanation:First, do 28 times two, since he's getting twice as many colored pencils. You should get 56. Then you take 11, and since he has 3 sisters you multiply it by three. Then you have 33. When you get this, you need to subtract 33 from 56. You should get 23 and that's your answer.
