A 2023 Ford F150 costs $62,500. My mother-in-law, Beth, is going to trade in her 2018 truck and get one. Shes going to get $14,000 for a trade-in, and shell finance the rest. The dealership offers a 5.8% loan, compounded monthly for 72 months. What will her monthly payments be? How much of her first payment will go towards the principal? How much will she pay for the truck in total over the 6 years?.
