The united states govermoment produced about 10.25 billion pennies in one year. how is 10.25 billion written in scientific notation?

First, we will put a decimal point at the end of number 10250000000.

In order to write number 10250000000. in scientific notation we need to move the decimal point from its current location (black dot) to the new position (red dot).

So, we need to move decimal point 10 places to the right. 
This means that the power of 10 will be positive 10.

Now we have that the

Number part = 1.0250000000 ( which can be written as 1.025 ) and

Exponent part = 10

ik how do do this just give me a few minutes and i will give it to

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
