Explanation:

Analyze Question 14: Importance of understanding inflation

• Inflation affects purchasing power, cost of living, interest rates, and investment decisions.
• Therefore, it has a significant impact on the overall economy and the daily lives of individuals.

Analyze Question 15: Opportunity costs of making breakfast at home

• Opportunity cost is the value of the next best alternative foregone when making a choice.
• Mia chose to make breakfast at home instead of grabbing a quick sandwich from a café.
• The direct alternatives/benefits foregone from the café option are: having a quick meal before her workout, and saving the time spent cooking.
• Cleaning up is a direct cost of her choice, not a foregone benefit of the alternative. Enjoying the breakfast more is a benefit of her choice, not a cost.

Analyze Question 16: Characteristics of a perfectly competitive market

• Perfect competition requires: many buyers and sellers, identical (homogeneous) goods, free entry and exit, and perfect information.

Analyze Question 17: Trade-off of choosing gym over studying

• A trade-off involves giving up one benefit or advantage to gain another.
• By choosing the gym instead of studying, Alex directly gives up study time, which means he will not have as much time to study for the exam.
