Reduced Fat Skippy peanut butter contains 12 g of fat per serving.
Reduced fat must have at least 25% less fat than the regular item.
Let reg = the fat content of the regular Skippy
If I subtract 25% of the regular fat content, I should get 12 or under grams of fat
12+=+reg+-+.25%2Areg
12+=+reg%281+-+.25%29
12+=+reg%2A.75
12%2A%284%2F3%29+=+reg
reg+=+16
Note that Reduced fat must have AT LEAST 25% less fat
Let's say it has 26% less fat
12+=+reg+-+.26%2Areg
12+=+reg%2A.74
reg+=+12+%2F+.74
reg+=+16.21
If reduced fat Skippy has 99% less fat, then
12+=+reg+-+.99%2Areg
12+=+reg%2A.01
reg+=+12+%2F+.01
reg+=+1200
So, the regular Skippy could have anywhere from 16 to 1200 grams of fat per
serving
