positive integer y is 50 percent of 50 percent of positive integer x , and y percent of x equals 4 . what is the value of x ?
"y = 0.5 * 0.5 * x = x / 4 y % * x = 4 ( y / 100 ) * x = 4 ( x / 400 ) * x = 4 x ^ 2 = 4 * 400 x = 40 the answer is a ."
multiply(multiply(divide(50, 4), divide(50, 4)), const_1000)
