It is estimated that approximately one-half of all aluminum cans will be recycled each year. if a soft drink company produces 350,000 cans one year, how many cans are still in use after 4 years of recycling and re-using, using this function? nt = 350,000(0.52)t a 87,500 b 25,591 c 175,000 d 21,875

First we rewrite the function correctly:
 Nt = 350,000 (0.52) ^ t
 Then, we substitute the number of years in the function to find the final value.
 So we have that for t = 4:
 Nt = 350,000 (0.52) ^ (4)
 Nt = 25590,656
 Nearest whole number:
 Nt = 25591
 
 after 4 years of recycling and re-using
 Nt = 25591
 cans are still in use
 B 25,591

Ibelieve the answer is pollen contains the sperm cell because the flower only has female parts and the pollen is the male part of the flower i believe
