We are given
total number of units sold =450
price of per unit =$ 40
average cost of per unit =$ 33
we know that
profit per unit = price per unit - average cost per unit
now, we can plug value
profit per unit = $40- $33
profit per unit = $7
now, we can find total profit
total profit = profit per unit * total number of units
now, we can plug values
and we get
total profit =[tex] 7*450 [/tex]
total profit =$ [tex] 3150 [/tex].................Answer
