steps to solve problem

Question

A student moves into a bigger apartment that rents for $450 per month. That rent is $200 less than twice what she had been paying. Find her former rent.

Answer 1

Let x = former rent

 

2x - 200 represents the new apartment (200 less than twice what she had been paying)

 

Since we know the new apartment is $450/month, we set up the equation:

 

2x - 200 = 450 and solve for x.

2x = 650

x = 325

 

Thus, the old rent was $325/month.
