Step-by-step explanation:
Substitute the value of the words (abcdef) into the equation given and you can solve it.
Answer:
y = 6
Step-by-step explanation:
We need to interpret the question
y varies directly as x
y varies x
To equate it, we need to add a constant K
y = K/x
Using the information we are provided with
y = 9
x = 3/2
insert into
y = Kx
9 = K * 3/2
9 = 3K/ 2
3K = 9 *2
3k = 18
To get K, divide through by 3
3K/3 = 18/3
K = 6
Since we've gotten our K = 6
y = Kx
Using the new information
y = ?
x = 1
K = 6
y = 6* 1
y = 6
The new y = 6 , x =1
<h2>Solution (a) :-</h2>
Let the cost of the less expensive comic book be x .
Then :-
Using this equation , we can find the cost of the less expensive comic book .
Price of the less expensive book :-
Cost of the less expensive book is 107 .
Therefore , the epice of the less expensive book = $ 107 .
<h2>Solution (b) :-</h2>
Cost of the more expensive book = 11x
Which means :-
Therefore , the price of the more expensive book = $ 1177 .
