• Option 1:

o Total amount at the end of two years: $1,150
BR
• Option 2:
o Loan $500 to a friend for one year and receive $600
o Deposit $500 (left over) in a back at 3% for two years:

$500(1.03)(1.03) = $530.45
AR
o Deposit $600 received from your friend at 3% per year for a year:

$600(1.03) = $618
Total amount at the end of two years:

$530.45 + $618 = $1,148.45
Y
These two options are about the same. But considering the trustworthiness, you
could go with Option 2.

2.3
(a)

• Current assets = $150,000 + $200,000 + $150,000 + $50,000 + $30,000
XE
= $580,000
• Current liabilities = $50,000 + $100,000 + $80,000 = $230,000
• Working capital = $580,000 - $230,000 = $350,000
• Shareholder’s equity = $100,000 + $150,000 + $150,000 + $70,000
= $470,000
LI
(b) EPS = $500,000/10,000 = $50 per share

(c) Par value = $15; capital surplus = $150,000/10,000 = $15
BR

Market price = $15 + $15 = $30 per share
AR
2.4
(a) Shareholder’s equity in 2021 = $700 - $510 = $190(M)
Shareholder’s equity in 2022 = $900 - $640 = $260(M)

(b) Net working capital in 2021 = $100 - $60 = $40(M)
Net working capital in 2022 = $200 - $90 = $110(M)
Y
(c) The income taxes in year 2022:

($2,350 - $1,130-$420-$210) *0.35 = $206.5(M)

(d) $383.50 + $420=$803.50 (M)
(Cash from Operating activities = Net income + Depreciation)
