Answer:
D. $81,728
Explanation:
Let's first convert pounds to ounces.
4 pounds x (16 ounces / pound) = 64 ounces. (Remember that when we're converting from a larger unit, pounds, to a smaller one, ounces, we'll have more ounces than pounds, so this answer makes sense!)
Let's now get the cost of the gold.
64 oz x ($1277 / oz) = $81,728. (Wow, that's a lot of gold!)
