Mr. Ekwelu:

I need help with the following estimations.

1) How much would it cost to sink a borehole to serve about 200 students?

2) How much would it cost to purchase about 180 pairs of shoes for both girls and boys?

3) How much would it cost to construct a dormitory large enough to accommodate say 180 students or thereabout?

4) How much would it cost to supply school materials and essentials -bags, books etc.  for 180 students?

Your help is greatly appreciate.
