Question

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

Answer 1

You need to create 2 algebraic expressions, one for the cost of company A, one for the cost of company B.  Then set them equal to each other and solve for the variable. You set them equal to each other because the cost will be "the same".

 

 

Company A

 

$40 per day... so if x is the variable, the expression is "40x"

 

 

You try the expression for company B... 

 

 

 

40x = ___________

 

 

Solve for x (the day)
