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?  Choose the correct choice from the following options.
A) 110
B) 140
C) 220
D) 250
E) 500
Let B be the number of boys in the school.   98 = x140/100   140 = 0.5x   9800=0.5x^2   x^2 = 19600   x = 140   The answer is 140.
