Answer:
311 
Step-by-step explanation:
Taking a pizza to be a circle
Area of big pizza be x abd are of small pizza be y
hence difference = x-y
Area of a circle = 
where r is the radius
taking 
to be 3.14
hence area x = 3.14 (
*) = 1017.36
Area y = 3.14 (
* )= 706.5
x-y = 1017.36- 706.5 =310.86
310.86
So to find the answer to this, you have to consider that
- half because half the pocket money (x) was spend on clothes, then plus 9 because that's how much extra she gained and 13 because that was the result of all the changes.
To solve this, first subtract 9 from both side, which leaves you with
and
is the same as
, so to solve this, multiply both sides of the equation by two, resulting in
. SO from this we can conclude that the weekly allowance is $8
