I think the answer is $2.01 per 1ft of redwood and pine
282/2
=141
$141/70ft ÷ 70/70
=$20.1 per 1ft
Depending on your graph go down 4 an across until u get to the other dot
To analyze the problem first is to arrange the equations according to their uses:
# of taxi accident y = -143.3X^2+1823.3x+6820
# of injuries y = -416.72X^2+4416.7x+8500
So the answer if X = 9 will be represented by 1999
# of taxi accident y = 11622.4
# of injuries y = 14495.98
I hope you understand the answer and feel free to ask for more.
