Problem: if 1.5 x = 0.04 y , then the value of ( y - x ) ( y + x ) is :
Rationale: "let us assume x = 1 and y = 37.5 then 1.5 ( x ) = 0.04 ( y ) that is 1.5 ( 1 ) = 0.04 ( 37.5 ) = 1.5 = 1.5 therfore from given equation ( 37.5 - 1 ) ( 37.5 + 1 ) = ( 36.5 ) ( 38.5 ) = 1405.25 answer : a"
annotated_formula: divide(subtract(divide(multiply(1.5, const_100), const_2), const_2), add(divide(multiply(1.5, const_100), const_2), const_2))
