1 15 pts] Your artist roommate has made a small bronze 2kg statue of Harry the Husky (the football mascot). The statue 1 pot vanus took 2 kg of bronze to cast and one pot of varnish for the ($15) coat. The Athletic Department would like your roommate to build a larger scaled model that is five times larger than the original statue. If each pot of varnish is $15, how much 1 A should your roommate bill the athletic department? A) $15 B) $75 C) $250 D) $375 E) $1875 ly 0.74x + 0.65 2.

Answer 1

1. The larger model is a scaled model of the smaller one and this means the dimensions of the larger statue will be 5 times larger in each dimension and as so the surface area of the larger statue will be 25 times larger than the smaller one. The amount of varnish will scale with the surface area, so, the amount of varnish can needed for the larger statue will be 25.

Hence cost of painting the larger statue = $ (25*15) = $ 375

So, option (D).
