Question

Lauren spends 30% of her monthly income on rent. If she pays $810 for rent each month, what is her monthly income?

Answer 1

ANSWER:

The monthly income of lauren is $2700

SOLUTION:

Given that, Lauren spends 30% of her monthly income on rent

Let the monthly income of lauren be x.

Then, 30% of x = rent payment -- eqn  (1)

And also given that, lauren pays $810 for rent

rent payment = $810

Now, substitute rent payment in eqn (1)

30% of x =810

30% $\times$ x = 810

30/100 $\times$ x = 810

30 $\times$ x = 810 $\times$ 100

x = $\frac{81000}{30}$

x = 2700

Hence, the monthly salary of lauren is $2700.

Answer 2

For monthly income x we have

$\dfrac{810}{x} = 0.30$

$x = \dfrac{810}{0.30} = 2700$

Answer: $2700
