Answer:
$2000 a year.
Explanation:
Let's find the answer by using the following formula:
taxes=(house assessment)*(tax rate) for the initial conditions we have:
(1600/year)=(64000)*(tax rate)
(1600/year)/(64000)=(tax rate)
tax rate=0.025/year
For the current conditions we have:
taxes=(house assessment)*(tax rate)
taxes=(80000)*(0.025/year)
taxes=2000/year
So, the taxes will be $2000 a year.
