Answer and Explanation:
Nike
$18,627÷ ($2,494.7a+ $2,795.3b)/2
$18,627÷$2,645 = 7.0 times
Adidas
$10,299÷$1,415c+ $1,459d)/2
10,299÷$1 437= 7.2 times
2,566.2 – 71.5
b2,873.7 – 78.4
c1,527 – 112
d1,570 – 111
Average collection period
Nike
365÷7.0= 52.1 days
Adidas
365÷7.2
= 50.7 days
Therefore Adidas's accounts receivable turnover was about 3% higher [(7.2 – 7.0) ÷7.0] than that of Nike's, which simply means that Adidas was slightly more efficient than Nike in turning accounts receivable into cash.
