Option A. $1.28

Step-by-step explanation:

On Monday, a company stock closed at a price of $30.80 per share.

On Tuesday, it increased by $1.20 = 30.80 + 1.20 = $32.00

On Wednesday, it fell by 6.25% = 32 - ( 6.25% × 32 )

                                                     = 32 - ( 0.0625 × 32 ) = 32 - 2

On Wednesday, stock closed at   = $30.00

On Thursday, it fell by 4%         = 30 - ( 4% × 30 )

                                                   = 30 - ( 0.04 × 30 )

On Thursday, stock closed at   = 30 - 1.20 = $28.80

On Friday, it increased by 2.5% = 28.80 + ( 2.5% × 28.80 )

                                                     = 28.80 + ( 0.025 × 28.80 )

On Friday, stock closed at         = 28.80 + 0.72 = $29.52

The net change in the stock price from Monday to Friday

= 30.80 - 29.52 = $1.28
