The easiest way to solve this problem is to make a table, based on 100 total person
Prefer week ends Prefer week days Total
Female 10 55 65
Male 15 <span>20 </span>35
Total 25 75 100
The bold numbers are conclusions. The plain numbers are data.

O Subtract 12 from the product of 5 and 3, then multiply by 87
Answer:
63
Step-by-step explanation:
Set up the proportion
(6x+3)/17 = (8x - 1)/21 Cross Multiply
21 * (6x + 3) = 17 (8x - 1) Remove the brackets
126x + 63 = 136x - 17 Subtract 126x from both sides
63 = 136x - 126x - 17 Combine
63 = 10x - 17 Add 17 to both sides
63 + 17 = 10x Combine the left
80 = 10 x Divide by 10
80/10 = x
x = 8
Now you want 8x - 1
8*8 - 1 = 63
