Distribute. 11 x 2x is 22x. 11 x 3 is 33. So the answer is 22x +33.
I think that she wouldn't end up with “$14,400” she would end up with $76,800 if you multiply.
It is 9,000. You just have to add 3 zeros on the 9. Hope this helps!! :)
ANSWER
d.

EXPLANATION
A rational function is of the form:

where p(x) and q(x) are polynomial functions and q(x)≠0.
The first option contains the exponential function

This disqualifies it from being a rational function.
The second and third options are polynomial functions.
By definition, all polynomials are rational functions.
The last option is a typical rational function because it has at least an asymptote.
The most correct choice is

Find total collected by multiplying the amount per person by number of people:
1000 x 0.12 = $120.00
Total collected = $120.00
Divide total collected by number of people:
120.00 / 109 = $1.20
Each person gets $1.20
