Assume a machine that has a useful life of only one year costs $2,000. Assume, also, that net of such operating costs as power, taxes, and so forth, the additional revenue from the output of this machine is expected to be $2,300. The expected rate of return on this machine is:

15%

Explanation:

Return on assets (ROA) is a financial ratio that shows how effective the investments in assets has affected the company's income. Mathematically, It is the ratio of net income to total assets where the Net income is the total sales less total expense.

Given that the assets fetches the company an additional income of $2,300 and the cost is $2,000

Net income = $2,300 - $2,000

= $300

Rate of return = $300/$2000

= 0.15

= 15%

balanced lifestyle would be the type of lifestyle that fulfill all aspects of our life, including financial security, personal achievements, emotional balance, and intimate relationships with other people.

for me personally, the job that i would choose to achieve a balanced lifestyle is opening an online store.

online store can be managed from the comfort of our phone. if we are the owner of the store, we can determine our own working hours. we can arrange our working hours so we have time to do things such as taking care of children, cultivating romantic relationship, or do our hobby.
