tell me if im right :)
I'm pretty sure the answer is B, cuz they'd crash together and become 1unit instead of two
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:
<span>700x + 375y = 15000 .............(b)
</span>-
<span>700x + 700y = 18900 ...............(c)
</span>____________________________
0 -325y = -3900
y = -3900/-325 = 12
Recall x + y = 27, x + 12 = 27, x = 27 - 12 = 15
<span>C) 15 business class and 12 economy class</span>
