Given:
x = candy selling at 6 per pound
y = candy selling at 9 per pound
x + y = 15
6x + 9y = 15(7)
6x + 9y = 105
x = 15 - y
6(15-y) + 9y = 105
90 - 6y + 9y = 105
3y = 105 - 90
3y = 15
3y/3 = 15/3
y = 5
There should be 5 pounds of more expensive candy.
x = 15 - y
x = 15 - 5
x =10
There should be 10 pounds of less expensive candy.

Determine the number of adults
First, we need to calculate the number of children
Given that:
Substitute 170 for Girls in
Convert to fraction
Cross Multiply
Divide both sides by 2
So, the number of children are:
Next, we calculate the number of people in the cinema.
Substitute 765 for Children
Make People the subject.
If 3/5 are children, then 2/5 are adults.
So:
Well if you get back to the definition of a division, diving X by Y is finding out how many Ys you can have in a X.
It is clear that you will have more than X times Y if Y is less than 1 since dividing X by 1 is exactly X.
If you think of 10 and 1, you can divide 10 in exactly 10 portions of 1.
But you can divide it into 100 portions of 0,1.
And 100 is bigger than 10 of course.
Hope this helps.
