Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire song album = y dollars
Person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
Person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second we get
x = 0.99 dollars
Putting the value of x in the first equation we get
y = 12.96 - 3x
= 12.96 - 2.97
= 9.99 dollars
The answer to your problem is 11
It's already in the simplest form.
It is important to check all
the vital information’s given in the question.
<span>1 liter = 1000 ml
Then 6 liters = (1000 * 6) ml
= 6000 ml
Now
600 ml is the holding capacity of = 1 bottle
Then
6000 ml will be the holding capacity for =
(1/600) * 6000
= 10 bottles</span>
So a total of 10 bottles
having capacity of 600 ml can be filled with 6 liters. I hope the procedure is
easy enough for you to understand.
