Problem: positive integer y is 50 percent of 50 percent of positive integer x , and y percent of x equals 36 . what is the value of x ?
Rationale: "y = 0.5 * 0.5 * x = x / 4 y % * x = 36 ( y / 100 ) * x = 36 ( x / 400 ) * x = 36 x ^ 2 = 36 * 400 x = 120 the answer is e ."
annotated_formula: multiply(multiply(divide(50, 36), divide(50, 36)), const_1000)
