While mining Fred found a large metal bar that contained 24 ounces of nickel. Fred also determined that the bar was 80% nickel. What was the total weight of the metal bar in ounces?
pls explain it and answer

Not that I'm a chemistry expert but mathematically,The total weight of the bar is directly proportional to the known weight of the bar and the given percentage. I worked it out and found that the the total weight of the bar is 30 ounces. This is how I did it

Step-by-step explanation:

80:24

100:n

80(n)=100×24

A little equation and after it's solve the variable (n) will be equal to 30

The unit is added after calculations so that's how the answer is 30 ounces
