Answer:
Section A = $27,000
Section B = $14,800
Section C = $12,200
Explanation:
In this question,we have to assume the things
Like - Let the number of seats in section B be X and, in Section C be Y
So, Section A = Section B + Section C
That means, Section A = X + Y
And, Section A + Section B + Section C = $54,000
Means, X + Y + X + Y = $54,000
2X + 2Y = $54,000
So, X + Y = $27,000
And, the other equation is 20X + 15Y = $1,54,000 - 25 × 27,000
So, the both equation is
X + Y = $27,000
20X + 15Y = $479,000
Now multiply 20 in equation 1
So,
20X + 20Y = $540,000
20X + 15Y = $479,000
Now deduct the equation 1 from equation 2
So, the value would equal to
5Y = $61,000
Y = $12,200
X = $27,000 - $12,200 = $14,800
And, the Section A = X + Y = $27,000
