Answer:
a. ZTech will have a higher operating leverage because it has a higher fixed cost.
b. ZTech will have a higher profit since it has a higher operating leverage if the economy strengthens.
Step-by-step explanation:
Operating leverage measures the the extent to which a firm uses fixed cost to finance its operations. The higher the fixed cost, the higher the degree of operating leverage
If the economy strengthens, the firm with a higher degree of operating leverage earns a higher profit.
