1. A forest fire has been burning for several days. The burned area, in acres, is given by
the equation y =(4,800) 24, where d is the number of days since the area of the
fire was first measured.
a. Complete the table.
d, days since first
measurement
y, acres burned
since fire started
b. Look at the value of y = 4,800 - 20
when d = -1. What does it tell you
about the area burned in the fire?
What about when d = -3?
4800
0
-1
2400
-2
1200
-3
600
-5
150
C. How much area had the fire burned
a week before it measured 4,800
acres? Explain your reasoning.
