While mining, Sandy found a large metal bar that weighed 32 grams. Sandy was also able to determine that the bar contained 75% copper. How many grams of copper are in the metal bar? Round your answer to the nearest whole number if necessary. x Clear Undo Redo​

40%

Step-by-step explanation:

make 20*5=100 , total, 8*5 which makes 40

there would be 24 grams of copper.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
