I am not inclined to show work for someone to copy.

costeach= costperhour*time + fixedcost

In one, the fixed cost is zero.

find time when both are equal (set the two cost equations equal to each other).

then, for times greater than that, Company B is costlier, and for times less than that, Company A is costlier.
