Maddie buys stock that is worth $22 per share. On the first day, the value of the stock goes up 20%. On the second day, the value decreases by 10%. What is the value of each share at the end of the second day?

At the end of the second day, the value of the share is $23.76

Step-by-step explanation:

Maddie bought $22 worth of share

20% increase of $22 share in the first day

= 20/100 × 22

= $4.40

The total value at the end of the $22 + $4.40

= $26.40

On the second day, 10% decrease of $26.40 is

= 10/100 × $26.4

= $2.64

At the end of the second date, the value of the share is $26.40 - $2.64

= $23.76

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
