How many total grams of silver alloy is being mixed together?
what is the percent concentration of the resulting alloy
Yes, that's What we have to find. But there are steps involved in the solving process.

yes its very frustrating
So again, How many total grams of silver alloy is being mixed together?
Okay so, now What IS 80% of 25?
And What is 15% of 70?
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
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
