Company 1 says that they will complete the job for $12 per foot of fencing. Company 2 says that they will charge you $4500 for the first 500 feet of fencing and $25 for each additional foot. Determine the cost of fencing for both companies .Remember that both companies need to charge 6.35% sales tax. SHOW WORK

Answers

So Company 1 charges $6,000 dollars for 500 feet of fence.
Company 2 only charges $4500/500 or $9.00/foot up to 500 feet.

The difference of 6,000 - 4500 = $1,500 so using Company two you will get 60 more feet of fence then both companies break even. After 500 ft
Company 1 only charges $12.00 dollars a foot and Company 2 charges $25.00 a foot.

So if you need 500 ft Company 1 costs 6,000 + 391.80 tax
Company 2 costs 4,500 +293.85 tax
Question does not ask how many feet is going to be needed?

Answers

In order to put a number into scientific notation, you multiply or divide the number by multiples of 10 until your base number is between 1 and 10 then you raise the number to the negative or positive exponent in the amount that you used to multiply or divide the number... Let me show you...

0.000000106 millimeter

Every time you multiply by 10, you move the decimal one place to the right. In this case if you multiply by 10 seven times, the decimal moves 7 places to the right. Now you have

1.06 ... but you can't just change a number so you have to show how your number is equivalent to the original number. You do this with the exponents. If you raise the new number to the -7 exponent, it shows you have to move the decimal 7 places to the left to expand to your original number. So the scientific notation would be...
1.06 × 10^-7

*note- if you move the decimal to the left you would have a positive exponent. If you move it to the right you'll have a negative exponent.

0.000000106mm,

We move the decimal point from the left, until it gets to 1.06. And the point moves 7 times.

= 1.06 × 10⁻⁷ mm in scientific notation.
