You can put this solution on YOUR website!
30% of their monthly income is food and food costs $645.00.
Let m = monthly income.
%2830%2F100%29+%2A+m+=+645.00
next, multiply both sides by 100/30
+m+=+%28100%2F30%29+%2A+645.00+
solve the right side
+m+=+2150+
check: is 30% of this 645.00?
+%2830%2F100%29+%2A+2150+=+645+
it checks
monthly income = $2150.00
