Problema Solution
Although the people in a country throw 1500 aluminum cans in the trash every second of every day, 51.5% of the aluminum in the cans is recycled. If a beverage company distributes 450 comma 000450,000 cans, the amount of aluminum still in use after t years can be made into N cans, where Upper N left parenthesis t right parenthesis equals 450 comma 000 left parenthesis 0.515 right parenthesis Superscript tN(t)=450,000(0.515)t. Answer the following.
How many cans can be made from the original 450 comma 000450,000 cans after 55 years?
Answer provided by our tutors
N(t)=450,000(0.515)^t, where t is years
We need to find N(t) when t = 5 year:
N(55) = 450,000(0.515)^5
N(55) = 16,302 cans
16,302 cans can be made out of the original 450,000 cans after a time period of 5 years.
