Step-by-step explanation:

According to the Question,

Given that, The average number of subscribers to an online magazine each year from 2010 to 2015 is given in the table.

Year     Number of Subscribers   Percentage increase(20%)

2010         320000                      

2011          384000                        320000 × 1.20 = 384000

2012         460800                      384000  × 1.20 = 460800

2013         552960                       460800  × 1.20 = 552960

2014         663552                       552960 × 1.20 = 663552

2015         796262                       663552 × 1.20 = 796262

step-by-step explanation:

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.
