Cost of 12 notebooks = $9
Ratio of number of notebooks to its price
= 12:9
= 4:3 <em>(because we reduced it to the simplest form by dividing both numerator and denominator by 3)</em>
Let the cost of 8 notebooks be x.
Then, 8:x = 4:3
=> 8/x = 4/3
=> (8×3)/4 = x
=> 24/4 = x
=> 6 = x
So, the cost of 8 notebooks is $6.

Answer: The Athletic can other 12 volleyballs.
Step-by-step explanation:
If the director has $277 to spend then it means The director can spend at most $277.
Now one volleyball cost $22 and so we could represent the number of volleyballs you can buy by the expression 22x and including the shipping fee,we will extend the expression to 22x + 13 Now since the Director can spend up to $277 or less we can write the whole situation in a form of inequality as,
22x + 13 ≤ 277 Now solve for x to determine the number of volleyballs
-13 -13
22x
264
x
12
