Answer:
Please stop with this unless its for math. Others need more help :)
Step-by-step explanation:
Unless this was a real math problem please tell me <u>otherwise. </u>
Amount of tax paid = 43-40 = 3
Tax rate = 3/40 = 0.75
0.75 x 100 = 7.5%
Tax rate = 7.5%
Using an exponential function, it is found that it takes 5.42 years for the car to halve in value.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the car depreciates 12% a year in value, hence r = 0.12 and the equation is given by:
.
It halves in value at t years, for which A(t) = 0.5A(0), hence:






t = 5.42.
It takes 5.42 years for the car to halve in value.

Convert it then you will fine the weight.
This is a formula chart to help(i would’ve given you the answer but you didn’t give the sharp)
