The total entry price of the top of the eiffel tower during the low season of 95 euros for 4 students and five teachers the total entry price is 173 euros and for 6 students and 10 teachers. find total entry price of the eiffel tower for a group of three students and 4 teachers

74.30

Step-by-step explanation:

Let s = entry price for a student

Let t = entry price for a teacher

4s +5t = 95

6s+10t = 173

I will use elimination to solve this problem.

Multiply the first equation by -2

-2(4s +5t) = -2*95

Distribute

-8s - 10t = -190

Add this equation to the second equation to eliminate t

-8s - 10t = -190

6s+10t = 173

-2s = -17

Divide by -2

-2s/-2 = -17/-2

s = 8.50

Now we need to find t

4s +5t = 95

Substitute s=8.50

4(8.50) +5(t) = 95

34 +5t = 95

Subtract 34 from each side

34-34 +5t = 95-34

5t = 61

Divide by 5

5t/5 = 61/5

t = 12.20

We want to find the cost for 3 students and 4 teachers

3s+4t

3(8.50) + 4(12.20)

25.50 + 48.80

74.30

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
