So we first need to find the profit per unit, which means we need to find the number of units sold
profit = (sales price* quantity) - variable cost*quantity - fixed costs
plug in what we know
300,000 = (20q) - 12q-25,000
275,000 = 8q
q= 34,375 units produced. Then take profit/units = 300,000/34375 = 8.73 profit per unit
Now if we sell 5,000 more units, we would have 8.73*5000 = 43,636.36 additional profit
