Human population

The populations of two cities after t years can be modeled by -150t+50,000 and 50t+75,000. What is the difference in the populations of the towns when t=4?

Correct answer:

d =  25800

Step-by-step explanation:

t=4  p1=150 t+50000=150 4+50000=49400 p2=50 t+75000=50 4+75000=75200  d = p1p2 = p2p1 d=p2p1=7520049400=25800
