Assuming that each person's contribution was a percentage of a fixed amount x (for example, each person contributed a percentage from their salary, and all contributors were on the same salary) we can write the following equation (converting all percentages to decimal fractions):
118×0.04x+13×0.03x+16×0.02x+1×0.0184x+1×0.018x+2×0.015x=
4.72x+0.39x+0.32x+0.0184x+0.018x+0.03x=5.4964x=136,809.40.
Therefore x=24,890.73 approx.
Therefore 118 people each contributed 995.63, total contribution=117,484.24;
13 each contributed 746.72, total contribution=9,707.38;
16 each contributed 497.81, total contribution=7,965.03;
1 contributed 458;
1 contributed 448.03;
2 each contributed 373.36, total contribution=746.72.
Overall contribution=136,809.40.
