Answer: The correct answer is Option C.
Explanation:
We know that:
Number of days in a year = 365 days
We are given:
Number of people = 300 million
In 2 days, 1 aluminium cans are consumed.
So, in 365 days, number of aluminium cans consumed are = [tex]\frac{1}{2}\times 365=182.5[/tex]
It is also given:
1 aluminium can weighs 1 ounce
Converting this into tons, we use the conversion factor:
[tex]1oz=3.125\times 10^{-5}tons[/tex]
Amount of aluminium needed will be = Number of people × Number of cans consumed × Mass of aluminium in 1 can
Amount of aluminium needed will be = [tex][300\text{ million}\times 182.5\times 3.125\times 10^{-5}\text{ tons}]=1.7\text{ million tons}[/tex]
Hence, the correct answer is Option C.
Answer:
C 1.7 million tons
Explanation:
First we have to divide the number of days in a year by two to calculate the number of aluminum canes that one american uses a year:
365/2=182,5
So then we have that 182,5 is the number of cans that an american uses a year, we multiply that by 300 million americans:
182,5*300,000,000=5.475x10^10
So we use 5.475x10^10 is the amount of ounces that we use in cans now we just convert that to tons:
5.475x10^10*3.125e-5=1,710,937.5
So the tons are 1,710,937.5 from the total number of cans that are used by the 300 million americans.
