Answer:
1.52
Step-by-step explanation:
We're rounding to the nearest hundredth.
According to the rules of rounding, we need to look 1 digit place to the right. If that digit is 5, then we round up. Otherwise, we round down.
For 1.518, we need to look at 8 (since we're rounding to the hundredth).
, so we round the hundredths digit up.
So 1.518 rounds up to 1.52

Part 1)
Part 2)
The composition f(g(x)) represents the amount of money Raul earns per ticket given the amount of hours Raul works
Step-by-step explanation:
We are given the two functions:
Which represents the amount of money Raul earns per ticket and:
Which represents the number of tickets Raul sells per hour.
Part 1)
We want to find f(g(x)).
So, we substitute g(x) for f(x). This yields:
This can be expanded a simplified as such:
Part 2)
Recall that f(x) outputs the amount of money Raul earns per ticket.
And g(x) inputs the amount of hours Raul works.
When we composed f(g(x)), the input and output stayed the same.
So, f(g(x)) represents the amount of money Raul earns per ticket (output of f(x)) <em>given</em> the amount of hours Raul works (input of g(x)).
