Answer: a. The firm must purchase lumpy assets to achieve the increase in sales.
Step-by-step explanation:
EvenFlo Pipes needs to sell more pipes in order to see an increase in sales. Assuming they are the producers, they will need to produce more pipes than they have been doing and this will need them to increase their production capacity.
To do so they would have to invest in fixed assets as these are what produce pipes. This is why the firm will have to purchase lumpy assets that will help them produce and sell more pipes.
