Answer 1

The net change in stock from Monday to Friday is $ 3.2956.

Step-by-step explanation:

Given,

Price of stock on Monday = $ 30.80

On Tuesday, it increased by $1.20 per share.

On Wednesday, it fell by 6.25%

On Thursday, it fell by 4%

On Friday, it increased by 2.5%

To find the net change from Monday to Friday.

Formula:

If the value increased by a% in x, the value will be = x×$\frac{(100+a)}{100}$

If the value decreased by a% in x, the value will be = x×$\frac{(100-a)}{100}$

Solution:

Price of stock on Monday = $ 30.80

Price of stock on Tuesday = $ 30.80×1.20 = $ 36.96

Price of stock on Wednesday = $ 36.96×$\frac{(100-6.25)}{100}$

= $ 34.65

Price of stock on Thursday = $ 34.65×$\frac{(100-4)}{100}$

= $ 33.264

Price of stock on Friday = $ 33.264×$\frac{(100+2.5)}{100}$

= $ 34.0956

Hence,

The net change in stock from Monday to Friday is = $(34.0956-30.80)

= $ 3.2956

Answer 2

Answer: Price of stock on Wednesday = $ 36.96×

= $ 34.65

Price of stock on Thursday = $ 34.65×

= $ 33.264

Price of stock on Friday = $ 33.264×

= $ 34.0956

Hence,

The net change in stock from Monday to Friday is = $(34.0956-30.80)

= $ 3.2956
