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=88.5+90.2+94.8+98.54
=3724
=93
So, the average amount of tax paid by the school per year is 93 million dollars.
