Answer:
A personal budget provides <u>a detailed account</u> of income and expenses for a <u>period.</u>
Explanation:
A personal budget is a plan of how one intends to spend their income. It shows the source of income and the total on one side. The expenses are listed on a different side. Each expenditure item is listed and its estimated amount is indicated. The total of all incomes and expenses is shown on their respective sides.
A personal budget may be prepared for a regular income say monthly, weekly, or quarterly payments. It can also be prepared for irregular incomes such as loans, gifts, or bonuses.
Answer:
The correct answer is option B.
Explanation:
In a competitive industry there is no restriction on entry or exit of firms in the market. So, when in the short run the firms are enjoying super normal profits or positive economic profits, this would attract potential firms to join the industry in the long run.
As a result the industry supply will increase in the long run. The increase in supply would cause the price to fall. This would further contribute in reducing revenue and profit.
This process will continue till the profit is reduced to zero. If profit falls below zero, then firms incurring loss will exit the industry. Then again zero profits will be restored by reduction in supply and increase in price.
So, we can say that perfectly competitive firms will have zero economic profits or only normal profits in the long run.
