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. what is the entrance fee for one student?
a. $10.50
b. $17.46
c. $17.75
d. $61.21

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

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
