If the total bill is $85, and you want to leave a 15% tip, then you can calculate it as follows:
85 * 15%
= 85 * 15/100
= 85 * 0.15
= 12.75
The amount that should be left as a tip is D. $12.75.
Looking at your answer your function is correct.
If the software is telling you something's wrong, it has to be with the formatting; maybe they want you to simplify the second part of the function. If that is the case, use the distributive property:
0.25(x-200)+15
0.25*x-0.25*200+15
0.25x-50+15
0.25x-35
Answer:
Number of year = 13 year and 6 month approx.
Step-by-step explanation:
Given:
Amount invested = $80,000
Rate of interest = 6% compounded continuously
Future value of investment = $175,600
Find:
Number of year
Computation:
Future value of investment = Amount invested[1 + Rate of interest]ⁿ
175,600 = 80,000[1+6%]ⁿ
175,600 = 80,000[1+0.06]ⁿ
175,600 = 80,000[1.06]ⁿ
Number of year = 13.492 year
Number of year = 13 year and 6 month approx.

Answer:
See below
Step-by-step explanation:
With center , h,k given as 3,2
standard form is
(x-3)^2 + ( y-2)^2 = r^2
r^2 is distance from center to point given
distance formula r^2 = ( 3-5)^2 + (2-4)^2
r^2 = 8
so the equation is then (x-3)^2 + (y-2)^2 = 8
