A barista is mixing a house blend of coffee that is 25% light roast. If they are 8 pounds of the the light roast available, how much of the blend can the barista make?

Answer;

32 pounds of the blend can be made

Explanation;

If light roast is 25%, then the other part will be 100-25 = 75%

Now the ratio of the light roast to the other part will be;

25% to 75% = 1 to 3

So if light toast is 8 pounds, the other part will be 3 * 8 = 24 pounds

So the amount of blend to be made will be 8 pounds + 24 pounds = 32 pounds

2 is the final ! : )
