Charity donated by Tillman = $3540
Number of employees who donated = 118
Contribution of Tillman = 40%
Let the average contribution of employees be = x
Then the amount contributed by employees = 118x
Then contribution of Tillman =
![(40)/(100)*118x](https://img.qammunity.org/2019/formulas/mathematics/high-school/7lbi32ikbmvdf1sv881ltwygdrm58xidch.png)
As Tillman donated 3540 , then
![3540=(40)/(100)*118x](https://img.qammunity.org/2019/formulas/mathematics/high-school/2clhpdovtstowgzxi4z7r4hvboyu9tihi2.png)
![3540=47.20x](https://img.qammunity.org/2019/formulas/mathematics/high-school/djelypilr3ykbf4w72shj31mxx6n2eu5x3.png)
![x=75](https://img.qammunity.org/2019/formulas/mathematics/high-school/qdcd8dmfqwsmnetnx2f0b9ff85gudldgwu.png)
Hence, average contribution by each employee is $75.
Option C is correct.
