Answer:
decreased by $1.28
Explanation:
On Monday, a company stock closed at a price of = $30.80
On Tuesday, it increased by $1.20 per share.
The stock closed at a price = 30.80 + 1.20 = $32.00
On Wednesday, it fell by 6.25% = 32-(6.25% × 32)
= 32 -(0.0625 × 32)
= 32 - 2.00 = $30
The stock closed on Wednesday at a price = $30.00
On Thursday, it fell by another 4% = 30 -(4% × 30)
= 30 -(0.04 × 30)
= 30 - 1.20 = $28.80
The stock closed on Thursday at a price = $28.80
On Friday, it increased by 2.5% = 28.80 + (2.5% × 28.80)
= 28.80 + (0.025 × 28.80)
= 28.80 + 0.72 = $29.52
The stock closed on Friday at a price = $29.52
Net change in the stock price from Monday to Friday = 30.80 - 29.52
= $1.28
The stock decreased by $1.28 per share from Monday to Friday.
