Answer:
Dividend pay-out ratio = $1.50/$3 x 100 = 50%
Retention rate (b) = 50% = 0.5
Return on new investment (r) = 15% = 0.15
Growth rate = retention rate x return on new investment
Growth rate = 0.5 x 0.15
Growth rate = 0.075 = 7.5%
Explanation:
Since the dividend pay-out ratio is 50%, it implies that retention rate is 50%. Return on new investment is 15%. Growth rate is the product of retention rate and return on new investment.
