Kim spent 70% of her salary on expenses and saved $1200 what is her salary

Kim spend 70% of her salary. And kept 1 200 for her savings. Now, since 70% of her salaray goes to her expenses, I assumed that 1200 is the 30% of her salary.=> let's find out how much is her salary

:=> 30% =.30

=>.30x = 1 200=>

.30x /.30 = 1 200 /.30

=> x = 4000 dollars is her salary.
