Answer the following 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?
Step-by-step reasoning process: 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.
The answer is 12.

Answer the following question.
Nathan is buying decorations for his wedding reception. The reception hall will have 20 tables. Each table needs a linen tablecloth ($25 to rent), 4 place settings ($10 each to rent), and a centerpiece. Each centerpiece will have 10 roses ($5 each) and 15 lilies ($4 each). How much will the decorations cost?
Step-by-step reasoning process: First find how much the roses for one centerpiece cost: $5 / rose * 10 roses = $50. Then find how much the lilies for one centerpiece cost: $4 / rose * 15 roses = $60. Then find how much the table settings for one table cost: 4 settings * $10 / setting = $40. Then add the cost of both types of flowers, the place settings, and the tablecloth to find the total cost per table: $50 + $60 + $40 + $25 = $175. Then multiply the cost per table by the number of tables to find the total cost: $175 / table * 20 tables = $3500.
The answer is 3500.
