Answer:
In the park's pool there are 7 less chlorine tablets as compared to safety standards.
Step-by-step explanation:
Number of chlorine tablets in 2,000 gallons water = 3 tablets
Number of tablets in 1 gallon of water =
Number of tablet to be added in 10,000 gallons of water :
Number of chlorine tablets added by lifeguard in 10,000 gallon water=8 tablets
Tablets of chlorine to be more added =
=15 tablets - 8 tablets = 7 tablets
In the park's pool there are 7 less chlorine tablets as compared to safety standards.

<h3>Answer: </h3><h3>Overall balance for year 5 after taxes = $1350</h3><h3>The filled out table is shown in the attached image below</h3>
===============================================================
Work Shown:
10% = 10/100 = 0.10
10% of 1000 = 0.10*1000 = 100 is the amount of interest earned in year 1. This goes in the first row of column 1. The overall balance becomes 1000+100 = 1100 after we add on the interest earned. We will write 1100 in row1,column2.
Next, compute the tax: 30% of 100 = 0.30*100 = 30. The 30 will be written in row1,column3. Finally, we subtract the amount taxed (30) from the overall balance in column 2 (which was 1100). So 1100-30 = 1070 will be written in row1,column4.
After finishing row1, we should have these four values: 100, 1100, 30, 1070
----------------------------------------------
Now onto row 2
We earn the same amount in interest because we are not compounding. Write 100 in row2,column1.
The overall balance will be different. Instead of using 1000, we will use 1070 which was the figure in row1,column4. Add the amount of interest earned ($100) onto the updated balance ($1070) to get 1170. Write 1170 in row2,column2
The value in row2,column3 is the same as the value above it. This is because the amount of interest does not change, so the amount taxed doesn't change either. Basically we'll have 30s all the way down column 3. We'll also have 100s all the way down column 1.
Subtract 1170 and 30 to get 1140 which is the balance after taxes for year 2.
------------------------------------------------
Repeat these steps for the third, fourth, and fifth rows and you'll get what you see in the table below.
