Determine the coordinate of the 4th point
From the given parameters, we can see that the rectangle is either horizontal or vertical.
This is because:

and

To calculate the fourth point, we simply make use of:
and 
Substitute 1.5 for x2 in

Answer:
Each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses
Step-by-step explanation:
Let x denotes number of boxes to be sold by each scholar to raise enough money to cover the team's travel expenses.
Number of scholars = 7
Total number of boxes 
Total number of chocolate bars 
Price of 1 chocolate bar = $2
Price of
chocolate bars 
Also,
Total amount to be raised for travel expenses = $1680
So,

Therefore,
each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses
Quadratic formula is the bestt
by applying it
8x^2-13x+3
x^2-13x/8+3/8=0
x^2-13x/8=3/8
x^2-13x/8+169/256
=73/256
(x-13/16)^2
=73/25
so correct option is D
