the ratio of the number of females to males at a party was 1 : 2 but when 3 females and 3 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 - 3 ) = 2 x - 3 x = 6 there were 3 x = 18 people at the party originally . the answer is c ."
add(divide(subtract(multiply(multiply(3, 2), 3), multiply(3, 2)), 2), subtract(multiply(multiply(3, 2), 3), multiply(3, 2)))
