positive integer y is 50 percent of 50 percent of positive integer x , and y percent of x equals 16 . what is the value of x ?
"y = 0.5 * 0.5 * x = x / 4 y % * x = 16 ( y / 100 ) * x = 16 ( x / 400 ) * x = 16 x ^ 2 = 16 * 400 x = 80 the answer is c ."
multiply(multiply(divide(50, 16), divide(50, 16)), const_1000)
