The total cost, y, for Leah and x friends to go to an amusement park can be modeled by a
Katarina [22]

Answer:

Range of the function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}

Step-by-step explanation:

Given that:

Seating capacity of the car = 6

Entrance fee per person = $45.25

Parking fee per car = $10

Leah is accompanied by x friends.

So, the total cost can be modeled as the following linear function:

y=45.25x+10

Now, the value of x i.e. number of friends going with Leah can be any of the following:

0, 1, 2, 3, 4 or 5 (because maximum capacity of the car is 6).

Leah is also going.

So, total number of people can be 1, 2, 3, 4, 5 or 6.

Therefore, the table of x, y can be:

\begin{center}\begin{tabular}{ c c}x & y \\ 1 & 55.25  \\  2 & 100.50  \\   3 & 145.75  \\ 4 & 191  \\ 5 & 236.5   \\ 6 & 281.50   \\\end{tabular}\end{center}

Here, the value of y is nothing but the range of the function.

Therefore, the range of the linear function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}
