PLEASE HELP Carbon-14 is a radioactive substance that decays over time. This expression models the
percentage of carbon-14 that remains in a sample after t years:
100()***
What does the number 5,730 represent?
the number of years it takes for the carbon-14 to decay completely
the original amount of carbon-14 in the sample
the number of years it takes for half of the carbon-14 to decay
the amount of carbon-14 in the sample after 100 years

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
