On monday a company stock closed at a price of $30.80 per share. on tuesday it increased by $1.20 per share. on wednesday it fell by 6.25%. on thursday it fell by another 4% and on friday it increased by 2.5%. what is the net change in the stock price from monday to friday

Tuesday:
30.80 + 1.20 = 32.00

Falling by 6.25% means it ends up being 93.75% of what it used to be (100% - 6.25% = 93.75%)

Wednesday:
32.00 * 0.9375 = 30

Thursday:
30 * 0.96 = 28.8

Friday:
28.8 * 1.025 = 29.52

Net change means you subtract to get the difference.

Net change = Final - initial
= 29.52 - 30.80
= -1.28

The stock fell $1.28

The answer is option c.
