the ratio of the number of females to males at a party was 1 : 2 but when 4 females and 4 males left , the ratio became 1 : 3 . how many people were at the party originally ?
"the total number of people are x females + 2 x males . 3 * ( x - 4 ) = 2 x - 4 x = 8 there were 3 x = 24 people at the party originally . the answer is c ."
add(divide(subtract(multiply(multiply(4, 2), 3), multiply(4, 2)), 2), subtract(multiply(multiply(4, 2), 3), multiply(4, 2)))
