Answer 2

To me, nothing is correct but if you change the number on option A, you can get the right equation
\(4k + 2m \leq 400\)

Answer 3

so is a my answer?

Answer 4

nope, have to change into that inequality because they ask about the number of hours to make keyboard and mice. If you don't change the inequality, option A is not correct though.

Answer 5

so would it be b?
