Question

a=2.6t
A= lbs of garbage
t=days of average man
Graph t>0

how many days dose it take for an average man to produce 150lbs of garbage.

Answer 1

for t>0 the t=1,2,3,........,n
plug in the equation values of t =1,t=2 and t=3 to get general coordinates of graph, from here you can plot
e.g for t=1 a = 2.6 so coordinates (1,2.6) and so forth.
for the second part:
a =2.6t
150 =2.6t,
now just find t
