[Question]: Ginger owns a flower shop, where she sells roses, lilacs, and gardenias. On Tuesday, she sold three times more roses than lilacs, and half as many gardenias as lilacs. If she sold 10 lilacs, what is the total number of flowers sold on Tuesday?
[Answer]: With 10 lilacs sold, three times more roses than lilacs is 3 * 10 = 30 roses. Half as many gardenias as lilacs is 10 / 2 = 5 gardenias. In total, there were 10 + 30 + 5 = 45 flowers sold on Tuesday.
So the answer is 45.

[Question]: In a glee club, there are two times as many female than male members. How many female members are there if there are 18 members in the club?
[Answer]: The club has a female group which has twice as many members as the male group, so there are 2 + 1 = 3 groups in the club. There are 18 members in the club, which means there are 18 / 3 = 6 members per group. Since the number of female members consists of two groups, then there are 6 * 2 = 12 female members in the club.
So the answer is 12.

So the answer is 15.
