Answer:
$1,200
Explanation:
The reason is that the net present value of the decision to buy delivery van is:
NPV = Present Value of Net Savings - Investment
Here
Present Value of Net Savings are $51,200
Investment is $50,000
By putting values in the above equation, we have:
= $51,200 - $50,000 = $1,200
This means that the cost of the van must not exceed by $1,200 at a 20% yield because it will alter the decision of purchasing the delivery van.
