The actual airplane wing is 24 times bigger than her first drawing.
24*4=96
The actual airplane wing is 96 inches long.
96/12=8
The actual airplane wing is 8 feet long.
The scale of her advertisement is 10 in : 96 in.
That reduces to 5 in :48 in.
8x - y = 54
8x + 2y = 60
subtracting, we get -3y = -6
y = 2
x = 7
Answer is (c) (7,2)
