Answer:
Step-by-step explanation:
The equations we want to graph are one for the revenue, and one for the number of items sold.
__
<h3>revenue</h3>The revenue from each lollipop is $1, so the revenue in dollars from selling x of them is 1·x = x. The revenue from each bag of chips is $1.50, so the revenue from selling y of them is 1.50·y = 1.5y. The total revenue from selling x lollipops and y bags of chips is ...
x +1.5y = 30 . . . . . dollars
__
<h3>item count</h3>The total number of items sold is ...
x + y = 26
__
<h3>solution</h3>The graph shows the solution to these two equations is ...
(x, y) = (18, 8)
The number of lollipops sold is 18; the number of bags of chips sold is 8.
Given:
Arnold has $24 to spend at the movies.
Ticket = $12
Popcorn is double the price of the soda.
The soda and candy bar are same price.
To find:
The price for the soda.
Solution:
Let x be the price of soda.
According to the question,
Price of candy = Price of soda = x
Price of popcorn = 2(price of soda) = 2x
Total amount = Ticket + Popcorn + Soda + Candy
Divide both sides by 4.
Therefore, the price of soda is $3.
