C
Step-by-step explanation:
The book at store A is $13.
5% tax means you pay 5 cents extra per dollar.
13*5= 65.
So so far your total is $13.65
The shipping fee is $3
$3+$13.65= $16.65
The book at store B is 15% off, with no extra charge
%15 of $19 is 2.85.
19-2.85 is 16.15

Answer:
1).
= (200 -
)
2). Inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
Step-by-step explanation:
Function representing the maximum heart rate is,
f(x) = 0.85(220 - x)
Here x = age of the client
Equation form of the function will be,
y = 0.85(220 - x)
To get the inverse of the given function, replace 'x' by 'y' and 'y' by 'x' and solve for y.
x = 0.85(220 - y)
220 - y = 
y = 220 - 
Now convert this equation into a function.
= (200 -
)
Here inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
Area of circle = pi r^2 = 81pi
1/3 of circle = 81pi / 3 = 27 pi units^2
answer
B. 27 pi units^2
