Answer:
The final price of share is $84
Explanation:
Initial price of share = $ 80
The price of share is dropped by 15% on Tuesday
Drop in share = 15 % of 80 = 0.15×80 = $12
Price of share after 15% drop in price = $80 -$12 = $ 68
Price of share increased by $7 on Wednesday
Price of share on Wednesday = $68 +$7 =$ 75
on Thursday the price of share was increased by 12%
So the price of share on Thursday = price of share + 12 % of price of share
= $75 +12 % of $ 75
= $75 +0.12 ×$ 75
= $ 75 +$9 = $ 84
The final price of share is $84
