Just input -3.5 and -12.8 into the expression: -c + d -(-3.5) + -12.8 3.5 - 12.8 Can you subtract those? @birvin73

OpenStudy (anonymous):

3.5+12.8

OpenStudy (anonymous):

-12.8

OpenStudy (secret-ninja):

Just plug in the amounts. -3.5 is changed to positive because it is already -c. This gives you: 3.5+ (-12.8)= -9.3 Your answer is D.
