Answer:
x - 79.25
Step-by-step explanation:
Let x represent the original amount of money that Ms. Liu had in her bank account.
Find how much money she spent on gasoline, by multiplying 15.85 by 5:
15.85(5)
= 79.25
To represent how much money she will have left, subtract this from x:
x - 79.25
So, the expression to find the change in her account is x - 79.25
Find the distance between the two points, and multiply it by 1/6.
