Answer:
90
Step-by-step explanation:
To solve this you first need to find the answer to both amounts of time. You would do this by substituting,
3 Hours
C(3)=45(3)+95
C(3)=135+95
C(3)=230
5 Hours
C(5)=45(5)+95
C(5)=225+95
C(5)=320
Now that you have both of the different sums you now just need to subtract them,
320-230=90
90 is your final answer.
