Answer:

52.8%

Step-by-step explanation:

The amount of alcohol is:

0.28 (6 pints) + 0.90 (4 pints) = 5.28 pints

So the concentration is:

5.28 pints / 10 pints × 100% = 52.8%.

Mr. Inahurry sold his house for $27,000, which is a 10% loss over what he originally paid for it. What did he pay for the house
Ainat [17]

Answer: $30,000

Step-by-step explanation:

If Mr. Inahurry had a 10% loss, it means that he paid X for the house and only got back 90% (100% - 10%) of what he paid.

This way X . 90% = 27,000

               X . 0.90 = 27,000

               X = 27,000/0.9

               X = 30,000

Counter-proof: 30,000 . 10% = 30,000 . 0.10 = 3,000

                          30,000 - 3,000 = 27,000
