Answer:
7 units
Step-by-step explanation:
If we want the profit to break even with the cost, then we must make the equations for cost and profit equal to each other.
3n-2=5+2n
First, we can subtract 2n from both sides and we get :
n-2=5
Next, we add 2 to both sides, and we get :
n=7
Therefore, we will need 7 units to break even with the cost and profit.
