Leah and Ashley go to the movie theater and purchase refreshments for their friends
klasskru [66]

Answer:

The required system of equations is:

5 m+   7  n = 113.75  

6 m +   14  n  =  185.50

The price of 1 bag of popcorn  = $10.5

The price of 1 drink   = $8.75

Step-by-step explanation:

Let us assume the cost of 1 bag of popcorn = $ m

And, the cost of 1 drink = $ n

Now, Leah spends a total of 113.75 on 5 bags of popcorn and 7 drinks.

Cost of 5 bags + 7 drinks = 5 m +   7  n  =  $ 113.75

⇒ 5 m+   7  n = 113.75   .. (1)

Also, Ashley spends a total of 185.50 on 6 bags of popcorn and 14 drinks

Cost of 6 bags + 14 drinks = 6 m +   14  n  =  $185.50

⇒  6 m +   14  n  =  185.50   .. (2)

So, here the system of equations that can be used to find the price of one bag of popcorn (m) and the price of one drink (n) are

5 m+   7  n = 113.75   .. (1)

6 m +   14  n  =  185.50   .. (2)

Now, to solve this, Multiply (1) with -2 and add with 2, we get:

-10m + 6m - 14 n + 14 n = 185.5 - 227.5

or, - 4  m = -42 , or m = 42/4 = 10.5

Putting the value of m = 10.5 in 5 m+   7  n = 113.75 , we get n = 8.75

Hence,  the price of 1 bag of popcorn  = m = $10.5

And the price of 1 drink  = n = $8.75
