Answer 1

Answer:

2 gallons of 15% alcohol  And  3 gallons of 10% alcohol

Step-by-step explanation:

Let, 2 gallons of 15% alcohol = 0.3

And, 3 gallons of 10% alcohol = 0.3

So, 2 gallons + 3 gallons = 5 gallons

Now 5 gallons of  12% = 0.6

Hence  we can say that,

Amount of 2 gallons of 15% alcohol and amount of 3 gallons of 10% alcohol makes Amount of 5 gallons of 12%

i.e 0.3 +0.3 = 0.6      Answer
