igor_vitrenko [27]

Answer:

Answer is option b, i.e. Passion for his invention.

Explanation:

Roland has almost all the qualities of a successful entrepreneur which includes an innovative mindset, ability to identify new opportunities, but he lacks in being passionate about what he desires to achieve. To start something new and follow one's dream one has to be passionate enough to be consistent and patient. Passion without patience is merely a dream which cannot be realized in true form.

levacccp [35]

Answer:

$130,000

Explanation:

Sarah is making use of the needs approach to determine how much life insurance to buy

The first step is to calculate the total amount of life insurance

Total amount of life insurance = Total needs - total assets

Total need = income needs + cash needs + special needs

= $140,000 + $30,000 + $100,000

= $270,000

Total assets= retirement plan + bank account + investment account

= $30,000 + $20,000 + $40,000

= $90,000

Total amount of life insurance = $270,000-$90,000

= $180,000

Since Sarah is covered by $50,000 group insurance by her employer then the additional life insurance that should be purchased can be calculated as follows

= $180,000 - $50,000

= $130,000
