let x be the fat in the original cookie.
let y be the fat in the reduced fat cookie.
---
the reduced fat cookie must have at least 15% less fat than the original cookie.
since (1-.15) = .85, this means that the maximum amount of fat in the reduced fat cookie is 85% of the amount of fat in the original cookie.
---
since x is the fat in the original cookie, then
y = .85*x would be the maximum amount of fat in the reduced fat cookie.
---
since the reduced fat cookie has 2 grams of fat in it, this equation becomes:
2 = .85*x
---
solving for x, we get:
x = 2/.85 = 2.352941176471 grams of fat in the original cookie.
---
so x = 2.352941176471 grams of fat is the minimum amount of fat in the original cookie, since the reduced fat cookie has 2 grams of fat in it.
---
we can conclude that the original cookie has at least 2.352941176471 of fat in it.
