You can put this solution on YOUR website!
Let x= slices of turkey LAST YEAR
And 400% of x you eat this year that equals to 12+slices, putting it into eqn:
400%(x)=12 ------------------------> working eqn
continuing:
we know we divide 400 by 100 to use into the eqn,
%28cross%28400%294%2Fcross%28100%29%29%28x%29=12
cross%284%29x%2Fcross%284%29=cross%2812%293%2Fcross%284%29
x=3 --------------> no. of slices ate last year
To check, simlpy 400% of 3: %28cross%28400%294%2Fcross%28100%29%29%283%29=12
Thank you,
