Answer:

3

Step-by-step explanation:

Since d represents the number of days the car is rented, Company A charges ...

40d

Company B charges ...

60 +20d

We want to find the value of d that makes these charges be the same value:

40d = 60 +20d

2d = 3 +d . . . . . . . divide by 20

d = 3 . . . . . . . . . . . subtract d

The cost is the same for 3 days.
