162 students represent x percent of the boys at a school . if the boys at the school make up 50 % of the total school population of x students , what is x ?
"let b be the number of boys in the school . 162 = xb / 100 b = 0.5 x 16200 = 0.5 x ^ 2 x ^ 2 = 32400 x = 180 the answer is c ."
sqrt(divide(multiply(162, const_100), divide(50, const_100)))
