The total cost is $919 for a person who purchases a car share and uses it for 45 hours.
Step-by-step explanation:
Given,
Yearly fee of car sharing = $109
Per hour fee = $18
Let,
x be the number of hours.
Total cost = Yearly fee + Per hour fee*Number of hours
Total cost = 18x+109
Number of hours = x = 45
[tex]Total\ cost=18(45)+109\\Total\ cost=810+109\\Total\ cost=919[/tex]
The total cost is $919 for a person who purchases a car share and uses it for 45 hours.
