98 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 . 98 = xb / 100 b = 0.5 x 9800 = 0.5 x ^ 2 x ^ 2 = 19600 x = 140 the answer is b ."
sqrt(divide(multiply(98, const_100), divide(50, const_100)))
