First, let's find how many page's Greta read per day. She read a total of 900 pages across 15 days, so she read:

Recall the definition of the composition between two functions:
Similarly, but not always the same:
Use the rules of correspondence of the functions f and g to find the compositions:
Then:
On the other hand:
Therefore, the answers are:
