Given:
$7/child
$10/adult
Total people = 700
Total money = $6,400
First, make two equations.
Let a = # of adults & Let c = # of children.
Let p = total people
1. a+c = 700
2. 10a+7c = 6,400
Then, rearrange the equation to solve for a variable.
c = 700-a
Substitute (700-a) for c, or the # of children in the second equation.
10a+(700-a) = 6400
9a+700 = 6400
9a+700-700 = 6400-700
9a = 5700
9a/9 = 5700/9
a = 633
= # of adults attended
700-633 = c = 66 
= # of children attended

Answer:
She needs 26 plastic bags.
Step-by-step explanation:
Given:
Amount of cups of snacks mix = 8 2/3
Rewriting 8 2/3 we get,
Amount of snacks mix =
Number of Cups in each bag =
She puts all the snacks mix in plastic bags
We need to find the number of plastic bags required to put all the snacks mix
Let number of plastic bag be x.
hence we can say that Number of Cups in each bag multiplied by number of plastic bag is equal to Amount of snacks mix.
Hence total number of plastic bags she needs is 26.
