Elise pays $21.75 for 5 student tickets to the fair. What is the cost of each student ticket?

$4.35 for each ticket

Step-by-step explanation:

You have to find the unit rate; how much does 1 student ticket cost?

We have to divide 21.75 ÷ 5.

21.75 ÷ 5 = 4.35.

So each ticket cost $4.35.

Hope this helps!

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
