Question

Alex has q stickers. Bernice has 4 more stickers than Alex. Charles has 2 more stickers than Bernice. They have 70 stickers altogether. Find the number of stickers Alex has.

Answer 1

Answer:

The number of stickers Alex has is 20.

Step-by-step explanation:

Given,

      Number of sticker with Alex $=q$

Bernice has 4 more stickers than Alex.

    So, Number of sticker with Bernice =$q+4.$

Charles has 2 more stickers than Bernice.

    So, Number of sticker with Charles=Number of sticker with Bernice + 2

                                                              =$(q+4)+2=q+4$

They have 70 stickers altogether.

Mathematically ,

                   Number of sticker with Alex+ Number of sticker with Bernice +Number of sticker with Charles=70

$q+(q+4)+(q+6)=70\\ \\ 3q+10=70\\ \\ 3q=70-10=60\\ \\ q=\frac{60}{3}=20$
