Answer: 15
Step-by-step explanation:
Let's define the concept of inverse functions.
If we have a function h(x), such that it has an inverse, and:
h(x) = y.
Then the inverse function j(x) must meet the following:
j(y) = x.
Now, we want to calculate:
h( j(15) ).
Let's suppose that:
j(15) = A.
(Where A can be any real number).
then, by the above relation, we must have that:
h(A) = 15.
Now we can replace j(15) by A in h(j(15)):
h( j(15) ) = h( A ) = 15.
Answer: 360g
120 --> 10
x ---> 30
120*30=10*x
3600= 10*x
x= 3600/10
x= 360

Answer:
Step-by-step explanation:
a) Tip = 15% of bill = 15% * 21 = 0.15 * 21 = $ 3.15
Amount including tips = 21 + 3.15 = $ 24.15
b) Tip = 15% of b = 0.15b
Amount including tips = b +0.15b
