Samuel and Christopher go to the movie theater and purchase refreshments for their friends.

Samuel spends a total of $34.00 on 6 bags of popcorn and 4 drinks.

Christopher spends a total of $66.25 on 12 bags of popcorn and 7 drinks.

Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink.

Using these equations, determine and state the price of a drink, to the nearest cent.

Drink=5.75

Popcorn=1.83

Percentage for drink=75.9%

Step-by-step explanation

Let the popcorn be p

the drinks be d

6p+4d=34 ... (1)

12p+7d=66.25 ... (2)

Multiply (1) by 2

12p+8d=72 ... (3)

Substrate (2) from (3)

d=5.75

Substitute the value for d into (1)

6p+4 (5.75) = 34

6p+23=34

Substrate 23 from both sides

6p=11

Divide both sides by 6

p=1.83

So for one drink=$5.75

For one popcorn=$1.83

To determine the% for drink

5.75+1.83=7.58

5.75/7.58 * 100

575/7.58

75.858~75.9%

The percentage for drink is 75.9%
