Question 1164573
2009=9 and 2014=14
we have ordered pairs (9, 3500) and (14, 4500)
that slope is 1000/5 or 200
point slope formula is y-y1=m(x-x1), m slope (x1, y1) point
y-3500=200(x-9)
y=200x-1800
y=200x+1700
in 2014, the cost was 200(14)+1700 or $4500, which we knew
7000=200x+1700
200x=5300
x=26.5
That means in 2026, the cost is $6900 and in 2027 it is $7100, so 2027.
