Answer:

30 adult's tickets were sold and 7 children's ticket were sold.    

Step-by-step explanation:

We are given the following information in the question:

Cost of Adult's tickets = $8

Cost of Children's ticket = $5

Total money collected = $275

Let x be the number of adult's tickets sold and y be the number of children's ticket sold.

Then, we can write this in the form of equation:

8x + 5y =275

The point (30,7) means that 30 adults ticket were sold and 7 children's ticket were sold.

Putting these value in the equation:

8x + 5y =275\\8\times 30 + 5\times 7 =240 + 35 = 275

which is true.

Thus, 30 adult's tickets were sold and 7 children's ticket were sold.

Answer:

  • 30 adult tickets
  • 7 children's tickets

Step-by-step explanation:

x and y are defined as the numbers of adult's tickets and the number of children's tickets, respectively. So x=30 means 30 adult tickets; y=7 means 7 children's tickets.

Revenue from sales of those numbers of tickets would be $275.

<h3>What is a function?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

The given functions are:-

F(x) =x²-2x+3

F(x) = -2x + 12

When we plot the graph of the function we will see that the line -2x +12 cut the parabola at points ( -3, 18 ) and ( 3, 6 ) so these are the ordered pairs of the two functions. The graph of the functions is also attached with the answer.

Sam paid $3.60 for 3/4 pound of his favorite trail-mix. What is the unit price (dollars per pound)?
jekas [21]

Answer:

So the unit price of the trail - mix is $4.80 per pound

Step-by-step explanation:

Sam paid $3.60 for 3/4 pound of his favorite trail-mix.

What it means is that said paid for 3/4 = 0.75 of a pound for $3.60

So let's determine how much he could have paid for a complete pound

$3.60= 0.75 pound

X= 1 pound

$X*0.75 pound= $3.60*1 pound

$x= ($3.60*1 pound)/0.75 pound

$x=$3.60/0.75

$x= $4.80

So the unit price of the trail - mix is $4.80 per pound
