638-243 = 395 miles
rounding up, it would be 400 miles
He would have to sale $500,000
9% of $500,000 is $45,000
So $30,000 plus $45,000 is $75,000
I believe it would be answer A. because it says he has a total of 180 pieces and all those numbers on the right add up to be 180.
The answer is 272 + 102 which equals 374yd^2
