Question

Hans needs to rent a moving truck. Suppose Company A charges rate of $40 per day and Company B charges $60 fee plus $20 per day. For what number of days is the cost the same?

Answer 1

Let the number of day = x
Then you can write an equation: 40x = 60 + 20x
and when you solve this you get 20x = 60
so x = 3 days
