Answer:
15 business class and 12 economy class
Step-by-step explanation:
Let the x be the number of business class. y be the number of economy
x + y = 27 ...............(a)
700x + 375y = 15000 .............(b)
Multiply first equation by 700
700*x + 700*y = 700*27
700x + 700y = 18900 ...............(c)
Recall:
700x + 375y = 15000 .............(b)
-
700x + 700y = 18900 ...............(c)
____________________________
0 -325y = -3900
y = -3900/-325 = 12
Recall x + y = 27, x + 12 = 27, x = 27 - 12 = 15
the answer is 15 business class and 12 economy class
