Question

Haynes High School chartered buses for 60 students to go on a field trip. Valley High School chartered buses for 80 students.

Answer 1

Answer: $20

Step-by-step explanation:

Let 'x' be the cost of a ticket at Haynes

Let 'y' be the cost of a ticket at Valley

Since the total cost from both schools are the same, we can write it as:

$60x=80y$

Since the cost of tickets at Valley was $5 less than Haynes, we can write it as:

$y=x-5$

Now we have two equations, we can use to substitute into the other expression:

$60x=80y$

$60x=80(x-5)$ we substitute y in this equation with the other equation

$60x=80x-400$

$-20x =-400$

$x = 20$

Therefore the cost of the ticket at Haynes is $20 and the cost of the ticket at Valley is $15.
