The answer would be "A wider based triangle" because the x value is birth rate and it is increasing, so that's why we need to answer to say "wider"
Well the Regular Price is the price before the sale was added. So here's the work that I would put in and in the end, just divide by (1 - 0.38).
Price x (1 - 0.38) = Sale Price (529)
Price x 0.62 = 529
Price = 529 / 0.62 = 853.23
$853.23 was the Regular Price
This is pretty dark lol, but I would say "gunshot wound" I have never learned this but it is my best guess.
