Answer: f(t) = 15 - 1.1t
Step-by-step explanation:
Let t represent the number of hours since the candle was lit.
A 15-inch candle is lit and burns at a constant rate of 1.1 inches per hour. This means that in t hours, the candle that would have burnt is 1.1t
The length of the candle that would be left after t hours is expressed as
15 - 1.1t
suppose f is a function such that f(t) represents the remaining length of the candle (in inches) t hours after it was lit, then
f(t) = 15 - 1.1t
<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
