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
