Answer:
5/12
Step-by-step explanation:
1/4 + 1/6 = (6+4)/24 = 10/24 = 5/12
why +1/6?
because: - (-) = +
[1], [3] => a = 49,000/2 = 24,500 => b +c = 24,500 => c = 24,500 - b;
[2] => 25*24,500 + 20b + 15c = 1,052,000 => 20b + 15c = 1,027,500;
20b + 15*(24,500 - b) = 1,027,500 => 5b = 733,500 => b = 146,700 =>
c = - 122,200;
12 x 16 = 192. So, the room is 192 square feet.
