4. You decide that working full-time is not going to help you achieve the retirement dreams described above, so you need a side gig to increase your income. You determine that you could buy a food truck and drive around the city every weekend selling curly potatoes on a stick for the next 10 years. The truck will cost you $70,000 to buy and will need $1,500 of maintenance each year (except the last year), plus new tires in year 5 costing $2,500 and new cooking equipment costing $3,000 in year 7. If you use a discount rate of 5% (compounded quarterly), how much revenue must you make on average by the end of each year for the next 10 years for this venture to have a net present value of $200,000?
