<h3>Answer:
$186.03</h3>
===================================================
Explanation:
It costs $91.50 for the first 200 copies.
Roger needs 200 more copies to get to 400 total.
He's charged $42 per 100 copies at this point, so he is charged 42*2 = 84 extra dollars to do those extra 200 copies.
Before tax, his total is 91.50+84 = 175.50 dollars.
The sales tax will increase the bill by 6%
To increase by 6%, we use the multiplier 1.06
1.06*175.50 = 186.03
Or you can follow the steps shown in the next section.
-----------------
6% of 175.50 = 0.06*175.50 = 10.53
The sales tax is $10.53
175.50 + 10.53 = 186.03
-----------------
Whichever method you use, you should end up with an after-tax cost of $186.03
Answer is x=8
Step-by-step explanation:
add up all the sides and set it equal to 20
add all the x's and constants
subtract the constant from both sides
then multiply by the reciprocal of the fraction from both sides and you'll get x
Answer:
d-3
Step-by-step explanation:
thats the answer
Vertical, because when two angles are across from each other they are the same angle measurement.
