A certain college party is attended by both male and female students. The ratio of male to female students is 4 to 5. If 9 of the male students were to leave the party, the ratio would change to 1 to 2. How many total students are at the party? | [
"50",
"58",
"46",
"54"

If 9 males left, the ratio would be 1:2 = 5:10, so there would be 5k males and 10k females.
8k-5k = 9
k = 3
8k + 10k = 24 + 30 = 54
