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 ?

23

Step-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.

Step-by-step explanation:

28 * 2 = 56  < This shows how he got the new packet of pencils

11 + 11 + 11 = 33 < How much overall he gave to his sisters

56 - 33 = 23 < This is him when he gives the pencils

John has now 23 pencils
