Answer:
The weighted average number of shares used to compute earnings per share for 2018 is 160,000
Step-by-step explanation:
At the beginning of the year Vent would have had 180,000 shares less the two new 15,000 shares newly issued(180,000-15,000-15000)=150,000
Outstanding common stock at beginning of the year 150,000*12/12=150,000
Shares issued on July 1 15,000*6/12 =7500
Shares issued on November 1 15,000*2/12 =2,500
Weighted average number of shares 160,000
The number with which to compute earnings per share is 160,000 shares as shown above.
