Need help on this question.



Ali's salary was 5/6 of Teri's salary. After Ali and Teri each spent $1080, Ali then had 7/9 as much as money as Teri. How much was their combined income?

thanks.

Hi

Since Ali and Teri spent the same amount of money(1080), the difference in their salary did not change.

At first

Ali:Teri -----5:6 (Difference – 1) ------ 10:12 ((Difference – 2)

In the end

Ali:Teri -----7:9 (Difference – 2)

Make the difference in units the same.

3 units ------ 1080
1 unit ------ 360

Combined salary ------ 22*360 ------- 7920

Best wishes
