Answer
Explanation:
Step1: Calculate the stock price on Tuesday
Add the increase of $$1.20$ to the Monday closing price. $$P_{Tue} = $30.80 + $1.20 = $32.00$$
Step2: Calculate the stock price on Wednesday
Subtract the $6.25%$ decrease from the Tuesday price. $$P_{Wed} = $32.00 \times (1 - 0.0625) = $32.00 \times 0.9375 = $30.00$$
Step3: Calculate the stock price on Thursday
Subtract the $4%$ decrease from the Wednesday price. $$P_{Thu} = $30.00 \times (1 - 0.04) = $30.00 \times 0.96 = $28.80$$
Step4: Calculate the stock price on Friday
Add the $2.5%$ increase to the Thursday price. $$P_{Fri} = $28.80 \times (1 + 0.025) = $28.80 \times 1.025 = $29.52$$
Step5: Calculate the net change
Subtract the Monday price from the Friday price. $$\text{Net Change} = $29.52 - $30.80 = -$1.28$$
Answer:
A. -$1.28
