Answer:
The function, f(x) to model the value of the van can be expressed as follows;

Step-by-step explanation:
From the question, we have;
The amount at which Amrita bought the new delivery van, PV = $32,500
The annual rate of depreciation of the van, r = -12% per year
The Future Value, f(x), of the van after x years of ownership can be given according to the following formula

Therefore, the function, f(x) to model the value of the van after 'x' years of ownership can be expressed as follows;

150%. since you already have 6, that's 100%. the extra 3 is half of the 6, meaning that it would be 50%
