Let's solve it first by removing the dollar symbol (you should add it at the final answer though).
[tex]\downarrow[/tex]
[tex] \sf \: - 40 - 60 + 120 - 90 + 70[/tex]
Subtract 60 from -40 to get -100.
[tex] \sf \: -100+120-90+70 [/tex]
Add -100 and 120 to get 20.
[tex] \sf \: 20-90+70 [/tex]
Subtract 90 from 20 to get -70.
[tex] \sf \: -70+70 [/tex]
Add -70 and 70 to get 0.
[tex] \boxed{ \boxed{ \bf \: 0 \: dollars}}[/tex]
- The correct answer is $ 0.
