Answer:

120%

Step-by-step explanation:

Given that,

The diameter of the raw cookie is 2 1/2 inches i.e. 5/2 inches

After baking the cookie, the diameter is 5 1/2 inches i.e. 11/2inches

We need to find by what factor does the cookie expand.

$x=\dfrac{5\dfrac{1}{2}-2\dfrac{1}{2}}{2\dfrac{1}{2}}\times 100\\\\=\dfrac{\dfrac{11}{2}-\dfrac{5}{2}}{\dfrac{5}{2}}\times 100\\\\=120\%$

So, the cookie will expand 120%.
