Answer:
IGR = 9.1640%
Explanation:
[tex]IGR = \frac{ROA \times retention}{1-(ROA \times retention)}[/tex]
.45 dividend payout ratio
1 - .45 = .55 retention ratio
ROA = Return on Assets
[tex]\frac{Earning \: before\: interest\:and\: taxes}{Toal \: Assets}[/tex]
Income before taxes 6,200
Assets 11,820 + 28,800 = 40,620 Total Assets
ROA 6,200 / 40,620 = 0.15263417
[tex]IGR = \frac{ROA \times retention}{1-(ROA \times 0.retention)}[/tex]
[tex]IGR = \frac{0.15263471 \times .55}{1-(0.15263471 \times 0.55)}[/tex]
IGR = 0.09164031 = 9.1640%
