hero · Answer

How many total grams of silver alloy is being mixed together?

anonymous · Answer

what is the percent concentration of the resulting alloy

hero · Answer

Yes, that's What we have to find. But there are steps involved in the solving process.

anonymous · Answer

yes its very frustrating

hero · Answer

So again, How many total grams of silver alloy is being mixed together?

anonymous · Answer

95

hero · Answer

Good

hero · Answer

Okay so, now What IS 80% of 25?

anonymous · Answer

20

hero · Answer

And What is 15% of 70?

anonymous · Answer

10.5

hero · Answer

20 is the Concentration of 80% silver alloy
10. 5 Is the concentration Of 15% silver alloy

So what you do is add those amounts together and put it over the total grams of alloy mixed

Total concentration of silver alloy OVER total grams of alloy

hero · Answer

Then simplify the fraction AS necessary, set it equal to x/100 and solve for x
x represents the percent concentration of silver alloy in the mixture
