Solving algebra word problems

A family spends $660 a month for rent. This is 30% of the families monthly income. What is their monthly income?

0.3x = 660

Divide by 0.3

x = 2,200 per month.

I hope this information was very helpful.

Let,
monthly income = x,
then,
30% of x = $660,

x = 660/(30/100) = $2200 >================< ANSWER

(660/30)*100= $2200
