Sliva [168]

Answer:

A. cash collected is 442,500

B. Cash paid to suppliers is 62,000

Less: Increase in accounts receivable 50,000

Less: write off 7,500

total collection 442,500

add: decrease in accounts payable 17,000

total cash paid to suppliers is 62,000

kvv77 [185]

Answer:

0.4 or 40%

Explanation:

the formula used to calculate the reward variability ratio is:

reward variability ratio = (expected return - risk free rate) / standard deviation = (20% - 10%) / 25% = 10% / 25% = 0.4 = 40%
