The price of one bag of popcorn is $3.75
Step-by-step explanation:
Let,
x represent the cost of a bag of popcorn
y represent the cost of a drink.
According to given statement;
4x+12y=30 Eqn 1
x+6y=11.25 Eqn 2
Multplying Eqn 2 by 2
Subtracting Eqn 3 from Eqn 1
Dividing both sides by 2
4x+12y=30 and x+6y=11.25 can be used to find the price of one bag of popcorn and the price of one drink.
The price of one bag of popcorn is $3.75

Answer:
The table C correctly shows the ratio 8:1 for each grade
Step-by-step explanation:
Let
x ----> the number of students
y ----> the number of adults
we know that
<u><em>Verify each table</em></u>
Table A
grade 6
Multiply in cross
----> is not true
Table B
grade 6
Multiply in cross
----> is not true
Table C
<u><em>grade 6</em></u>
\frac{96}{12}=\frac{8}{1}
Multiply in cross
----> is true
<u><em>grade 7</em></u>
Multiply in cross
----> is true
<u><em>grade 8</em></u>
\frac{136}{17}=\frac{8}{1}
Multiply in cross
----> is true
therefore
The table C correctly shows the ratio 8:1 for each grade
Table D
<u><em>grade 6</em></u>
Multiply in cross
----> is not true
