Answer: 7.560 ounces
Step-by-step explanation:
Given : The weight of a metal bar = 8.15 ounces
Also, it is given that : 93% of the bar is silver.
We can write 93% as 0.93 [To convert percent into decimal or fraction , we divide it by 100.]
Now, the amount of silver in the metal bar = 93% of 5.15 ounces
Replace 'of' by '×' and '93%' by '0.93' , we get
The amount of silver in the metal bar = [tex]0.93\times8.15\text{ ounces}[/tex]
[tex]7.5795\approx7.560\text{ ounces}[/tex]
Hence, there are 7.560 ounces of silver in the metal bar.
