How many grams of an alloy containing 25% silver should be melted with 50 grams of an alloy containing 60% silver in order to obtain an alloy containing 50% silver?

20 grams of an alloy containing 25% silver has to be melted with 50 grams of an alloy containing 60% silver to obtain a final alloy containing 50% silver

Step-by-step explanation:

Hi

We define

, wich means alloy a has 50 grams containing 60% silver.

, wich means alloy b has x grams containing 25% silver.

So we can build an equiation , as half of the final alloy has to be silver. Then solving for x

Wich means 20 grams of an alloy containing 25% silver () has to be melted with 50 grams of an alloy containing 60% silver () to obtain a final alloy containing 50% silver.

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
