butter than Imani's cookies, 750/630, what Vic will think is therefore;

(A) Imani's cookies have too much butter

The amount of flour Imani uses for every 630 grams of butter = 750 grams

Required:

What Vic will think about the amount of butter in Imani's cookies

Solution;

$Ratio \ of \ butter \ per \ gram \ of \ flour \ in \ Vic's \ cookies = \dfrac{170 \, g}{250 \, g} = \dfrac{17}{25} = \mathbf{0.68}$

$Ratio \ of \ butter \ per \ gram \ of \ flour \ in \ Imani's\ cookies = \dfrac{630\, g}{750\, g} = \dfrac{17}{25} = \mathbf{0.84}$

Imani's cookies contains more cookies than Vic's cookies, what Vic will

think of the amount of butter in Imani's cookies is therefore;

(A) Imani's cookies have too much butter
