If each of them paid an extra of $4.
4 person paid $4 x 4 = $16 extra
The $16 is the share of the 5th person, which is also each person's share.
$16 x 5 = $80.
Answer: The total bill is $80.
Answer:
√b/a
Step-by-step explanation:
We have
-9 + 7 = -2
You can also rewrite this as
7 - 9 = -2
If it makes you more comfortable.
Hope this helps.
May be there is an operator missing in the first function, h(x). I will solve this in two ways, 1) as if the h(x) = 5x and 2) as if h(x) = 5 + x
1) If h(x) = 5x and k(x) = 1/x
Then (k o h) (x) = k ( h(x) ) = k(5x) = 1/(5x)
2) If h(x) = 5 + x and k (x) = 1/x
Then (k o h)(x) =k ( h(x) ) = k (5+x) = 1 / [5 + x]
I believe that the answer is 40 minutes because each 10% is 4 minutes.
