Answer:
It can be modeled with the equation but needs a starting population number to finish.
Step-by-step explanation:
To find the population in a future year, use the formula:
where A is the amount, p is the starting population, r is 2% or 0.02, and t is the number of years.
Since the population is increasing it is addition. Substitute r=0.02 and t=6. Without a starting population, we cannot find the population in 6 years.
As the question says that Tory knows for $5 he will get 3.45 euros.
Now for the euro trip he needs to know the rate of conversion or the rate of euros per dollar.
To find the rate of conversion we need to use unitary method.
As we know that at the given rate he gets,
3.45 euros for $5
or the other way around
euros
Now, using the unitary method we get,
euro
Therefore, at the given rate we can see that for each dollar Tory would get 0.69 euro.
