Question

A student moves into a bigger apartment that rents for $550 per month. That rent is $300 less than twice what she had been paying. Find her former rent in dollars.
$

Answer 1

Answer:

Step-by-step explanation:

Her former rent is $ x

Twice the former rent: 2*x = 2x

$300 less than 2x: 2x - 300

2x - 300 = 550

Add 300 to both sides

2x - 300 + 300 = 550  + 300

                    2x = 850

Divide both sides by 2

               2x/2 = 850/2

x = 425

Her former rent = $425

Answer 2

In this question, the older and newer rents of a student in two apartments in given. And some conditions and information is also provided,

GiveN:

• New rent = $ 550
• This is $ 300 less than twice the previous

We have find her rent in the previous apartment.

Let her previous rent be $ x

Then according to question,

➝ $ 550 = 2x - $ 300

Adding $ 300 both sides,

➝ $ 550 + $ 300 = 2x

Flipping it,

➝ 2x = $ 850

➝ x = $ 425

So, The previous rent of the student:

$\huge{ \boxed{ \bf{ \ \: 425}}}$

And we are done !!
