nearest thousandth)

Answer 1

0.93 X 8.15 = 7.5795 
ANSWER 7.58 ounces

Answer 2

Answer: The bar contains 7.578 ounces of silver.

Solution:

Ounce is the unit of mass, weight or volume of certain solids or things that are used as a measuring constant in Britain and USA. "One ounce" is equal to 28.35 grams. The size of one ounce will be equal to liquid in 1inch diameter sauce cup.

93% of the bar is silver, $93 \%=\frac{93}{100}$

Weight of the metal bar = 8.15 ounces

93% of the metal bar =$\frac{93}{100} \times 8.15$ = 7.5795 ounces

Rounding to nearest thousand = 7.578 ounces.
