Question

The expenditure in schools over 4 years is given. What is the average amount of tax per year that the schools had to pay during the given period?

• A. 73 million dollars
• B. 93 million dollars
• C. 80 million dollars
• D. 92.6 million dollars

Answer 1

The correct option is B 93 million dollars

From the table, we observe:

Tax paid for the year 2017 = 88.5 million dollars

Tax paid for the year 2018 = 90.2 million dollars

Tax paid for the year 2019 = 94.8 million dollars

Tax paid for the year 2020 = 98.5 million dollars

$Average=\frac{88.5+90.2+94.8+98.5}{4}$

$=\frac{372}{4}$

$=93$

So, the average amount of tax paid by the school per year is 93 million dollars.
