Answer: It is common that your eyes are not green
<u>Step-by-step explanation:</u>
Given an "if p, then q" statement (notation: p → q)
the contrapositive is " if not q, then not p" (notation: ~q → ~p)
In the given statement,
- p = your eyes are green
- q = it is not common
So,
- ~p = your eyes are not green
- ~q = it is common
Therefore, the contrapositive should be:
If <u>it is common </u>, then <u>your eyes are not green</u>.
But grammatically it sounds better to say,
"It is common that your eyes are not green"
Given:
Book club A charges $20 for membership and $2 per book rental.
Book club B charges $10 for membership and $3 per book rental.
To find:
The number of books for which the cost be the same at both book clubs.
Solution:

Book club A charges $20 for membership and $2 per book rental. So, the total cost is
...(i)
Book club B charges $10 for membership and $3 per book rental. So, the total cost is
...(ii)
Equating (i) and (ii), we get
The total cost is
Therefore, the total cost at both book clubs are same for 10 rental books and that cost is $40.
When pam saves 2, brother saves 5
so if Pam has 40
40/2 (the number of dollars Pam saves) = 20
20 x 5 = 100 ( the number of dollars her bro saves)
her bro has 100 dollars
hope this helps
basically divide 2 from 40 and then multiply the answer with 5, and you get the number of money her bro saves
hope this helps
