Answer:Ava will have a total of 8 trips to make to total of 25 kilometers
Step-by-step explanation:
Total distance that Ava has already cycled this year is 9 kilometers.
she plans to cycle 2 kilometers during each trip to work.
Let x represent her number of trips to work. Therefore, for Ava to make a total of 25 kilometers, it means that
2x + 9 = 25
Subtracting 9 from both sides of the equation, it becomes
2x + 9 - 8 = 25 - 9
2x = 16
x = 16/2 = 8
