Answer:

The cost of one drink is $2.5 and the cost of one bag of popcorn is $8.25

Step-by-step explanation:

Consider the provided information.

Let price of one drink is x and the price of one bag of popcorn is y.

Adam spends a total of $62.75 on 2 drinks and 7 bags of popcorn.

[tex]2x+7y=62.75[/tex]

[tex]2x=62.75-7y[/tex]......(1)

Ian spends a total of $43.00 on 4 drinks and 4 bags of popcorn.

[tex]4x+4y=43.00[/tex]

Now use substitute the value of 2x in above equation.

[tex]2(62.75-7y)+4y=43.00[/tex]

[tex]125.5-14y+4y=43.00[/tex]

[tex]-10y=43.00-125.5[/tex]

[tex]10y=82.5[/tex]

[tex]y=8.25[/tex]

Hence the value of y is $8.25

Now find the value of x as shown:

[tex]2x=62.75-7(8.25)[/tex]

[tex]2x=5[/tex]

[tex]x=2.5[/tex]

Hence, the cost of one drink is $2.5 and the cost of one bag of popcorn is $8.25
