Answer

Find out the what is the entrance fee for one student .

To prove

Let us assume that the entrance fee for the 25 student be x .

As given

Twenty-five members of the eighth grade class at Park Center Middle School are going to a museum and then to lunch.

Each student must pay an entrance fee to the museum and $7.25 for lunch.

The total cost for the trip is $443.75.

Than the equation

x + 25 × 7.25 = 443.75

x = 443.75 - 181.25

x = $262.5

Thus the entrance fee of the 25 students be $262.5

Entrance cost for one student = $10.5

Therefore the  entrance fee for one student be $10.5

Option (A) is correct .

Hence proved

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
