The city of Anvil is currently home to 21000 people, and the population has been growing at a continuous rate of 4% per year. The city of Brinker is currently home to 7000 people, and the population has been growing at a continuous rate of 5% per year. In how many years will the populations of the two towns be equal

They'll reach the same population in approximately 113.24 years.

Step-by-step explanation:

Since both population grows at an exponential rate, then their population over the years can be found as:

For the city of Anvil:

For the city of Brinker:

We need to find the value of "t" that satisfies:

They'll reach the same population in approximately 113.24 years.

d is correct

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
