The local amusement park is a popular field trip destination. this year the senior class at high school a and the senior class at high school b both planned trips there. the senior class at high school a rented and filled 6 vans and 10 buses with 376 students. high school b rented and filled 3 vans and 2 buses with 104 students. each van and each bus carried the same number of students. how many students can a van carry? how many students can a bus carry?

Number of students can a van  carry are 16 and number of students can a bus carry are 28 .

Step-by-step explanation:

The number of students a van carry be x .

The number of students a bus carry be y .

As given

The local amusement park is a popular field trip destination.

This year the senior class at High School A and the senior class at High School B both planned trips there.

The senior class at High School A rented and filled 6 vans and 10 buses with 376 students.

Equations becomes

6x + 10y = 376

As given

High School B rented and filled 3 vans and 2 buses with 104 students.

Equations becomes

3x + 2y = 104

Multiply 3x + 2y = 104 by 2 and subtracted from 6x + 10y = 376 .

6x - 6x + 10y - 4y = 376 - 208

6y = 168

y = 28

Putting the value of y in the equation 3x + 2y = 104 .

3x + 28 × 2 = 104

3x + 56 = 104

3x = 104 - 56

3x = 48

x = 16

Therefore the number of students can a van  carry are 16 and number of students can a bus carry are 28 .

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

the correct answer is c

good luck love
