Answer:

c 15 business class and 12 economy class

Explanation:

We can set up a system of equations.

First, we choose the variables and define them.

Let x = number of $375 tickets.

Let y = number of $700 tickets.

Equation of number of tickets:

x + y = 27

Equation of costs of tickets:

375x + 700y = 15000

Now we solve the system of equations by the addition method.

Multiply both sides of the top equation by -375 and write it below the second equation. Then add the equations.

375x + 700y = 15000

(+) -375x - 375y = -10125

---------------------------------------

325y = 4875

y = 15

x + y = 27

x + 15 = 27

x = 12
