People are paid to paint polygons.
There are eight people in the polygon painting posse.
All of the people paint at the same rate.
When all of the people are painting, they can paint all of the polygons in the palace in ten days.
The table shows the number of people painting each day:
|Day 1||Day 2||Day 4||All other days|
|Number of people painting||3||6||7||8|
Work out the total number of days taken to paint all of the polygons in the palace.
