If M is the number of Laptops sold by store B and store D together in March and N is the number of Laptops sold by store A and store E together in January, then (M - N) = ________.
A16 ✓ Correct
B30
C40
D24
Correct answer: (A) 16
Explanation
M is store B plus store D in March, that is 336 plus 530 equal to 866. N is store A plus store E in January, that is 430 plus 420 equal to 850. So M minus N is 866 minus 850, which is 16. So the answer is 16.
