Answer:

  31 5/8 pounds

Step-by-step explanation:

The total weight is ...

  9(2 7/8 lb) + 2(2 7/8 lb) = (2 7/8 lb)(9 +1) = (23/8 lb)(11) = 253/8 lb

  = 31 5/8 lb

The total of package weights is 31 5/8 pounds.

With an initial population of 1,000 and a growth rate of 3%, a population increases to 1,162 after 5 years, to 1,350 after 10 ye
densk [106]

Answer:

An annual increase of 3.24% of the population.

Step-by-step explanation:

The population did not increase by the same number each year, because:

First 5 years:

1000 - 1162 = 162 people

Second 5 years:

1350 - 1162 = 188 people

Third 5 years:

1568 - 1350 = 218 people

What it says is that numerically the same number of people did not increase every 5 years, but if I increase by the same percentage, to calculate this percentage we divide the new people by the number that there were originally, that is to say:

First 5 years:

162/1000 = 0.162 = 16.2%

Second 5 years:

188/1162 = 0.1618 = 16.2%

Third 5 years:

218/1350 = 0.1615 = 16.2%

Which means that per year I increase by:

16.2 / 5 = 3.24%
