Answer:
3.1% / 0.031
16
Explanation:
dividend yield = dividend per share / share price
$2.50 / $80 = 0.031 = 3.1%
Payout ratio = dividend per share / earning per share = 50% = 0.5
$2.5 / earning per share = 0.5
earning per share = $2.5 / 0.5 = $5
P / E = Stock price / earning per share = $80 / $5 = 16
