So, first: what is the absolute increase?

The absolute increase is: 40-25=15. So the absolute increase is 15.

Now, 15 is what percentage of 25?

we count this as follows:

 \frac{15}{25}= \frac{3}{5} =0.8

0.8*100%=80%.

So percent increase is 80%.

In a batch of 860 calculators, 9 were found to be defective. What is the probability that a calculator chosen at random will be defective? Write the probability as a percent. Round to the nearest tenth of a percent if necessary.

The given is 860 calculators with a possibility that 9 are defective. To calculate for simple probability, we should have a number of desired outcomes (890) and number of possible outcomes (9). To calculate this, we have: 9 divided by 890 which equals to 0.0104. To get the percentage, we multiply 0.0104 by 100 and we'll have 1.04%. So, there's a 1.04% probability that a calculator chosen at random will be defective.

How can you quickly calculate 20 percent of any bill amount?

First, convert the percent into a decimal. To do this, simply more the % sign two places to the left and make it into a decimal point.

20% = 0.20

Then we will let x be our bill amount.

Then multiply 0.20 and x together to get your answer.

So, 0.20 * x is your answer.
