If fixed costs are 30, variable costs per unit are Q + 3 and the demand function is P + 2Q = 50
show that the associated profit function is
π = −3Q2 + 47Q − 30.
Find the break-even values of Q and deduce the maximum profit.

step-by-step explanation:

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
