First department can choose the pair (delegate,alternate) by 7*6 = 42 ways.
Second department can choose the pair (delegate,alternate) by 10*9 = 90 ways.
Third department can choose the pair (delegate,alternate) by 6*5 = 30 ways.
Since these selections are INDEPENDENT, the resulting choice can be done in 42*90*30=113400

Answer:
The answer to your question is $473.2
Step-by-step explanation:
Data
Payment $0.48 / 0.5 mile
bonus $35 for 150 miles
Distance driven = 420 miles
Process
1.- Calculate the bonus
420 / 150 = 2.8 then he will receive 2 bonuses = 2 x $35
= $70
2.- Calculate the payment for every half mile
420 / 0.5 = 840
840 x 0.48 = $ 403.2
3.- Total payment before taxes
Payment = $403.2 + $70
= $473.2

those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below
that means, the squared variable is the "x", thus the form is

now, we know the vertex is at 0,1, and two x-intercepts of

thus

solve for "a", to see what that coefficient is, then plug it back in the vertex form equation
