163+ 37 = 200 people
4* 50 = 200 programs
There will be exactly enough programs for every person to get one
In one dimensions (i.e. with standard numbers and not points with more coordinates) the midpoint is the same as the average.
The average of two numbers is their sum divided by two.
So, we have -4+20=16. Divide this by two to get 8.
Based on the amount of oranges bought, those sold at a profit and those sold at a loss, the overall profit is 14.2%
<h3>What is the overall profit?</h3>
Assume that the buying price was $1 each.
The amount earned from 60% of them is:
= 60% x 100,000 x 1
= $60,000
The profit from selling 50% of the remaining is:
= (50% x 40,000) x 1.60
= $32,000
The loss from selling the other 50%:
= (50% x 40,000) x 0.90
= $22,222.22
Total selling price:
= 60,000 + 32,000 + 22,222.22
= $114,222.22
Total profit:
= (114,222.22 - 100,000) / 100,000
= 14.2%
