The given table and equation represent the cost for carnival rides.

equation: c = 15.5 + 12f

what ordered pairs are represented in this table? check all that apply.
(7, 99.5)
15.5 + 12(3)
(75.5, 5)
(3, 51.5)
(123.5, 9)

The ordered pairs that are presented are (7, 99.5) and (3, 51.5)

Step-by-step explanation:

We are given the cost function of the carnival rides as

which is a typical linear expression of the form where here , ,    and  . To check if an ordered pair i.e. a point , is represented by the table we can simply plug in the equivalent value in the equation, and check if the result matches the value.

So, lets assume that all points are given correctly and they are as follow:

Now let us check each point with our function as follow:

Point A

So point A is part of the equation.

Point B

So point B is NOT part of the equation.

Point C

So point C is part of the equation.

Point D

So point D is NOT part of the equation.

(7, 99.5) and (3, 51.5)

Step-by-step explanation:

A and D

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
