This formula describes the mathematical description of the best sandwich
(JE-NCE)±(A) = IV
--------------------------------------------------------------
JE = Q*T
NCE = Average number that people can't eat
A= WP - AP (if the result is -A you subtract, if positive add)
Q = ED * AvP
T = X/100 then T = X (if multiple then add together)
--------------------------------------------------------------
JE = joy eating
A = accesibility
NCE = Number that can't eat
IV = ingredient value
Q = quality
T = taste out of 100
WP = Wanted price
AP = actual price
ED = expiring date
AvP = avarage price
