The owners of a successful restaurant want a loan for $50,000 to renovate the kitchen and expand the dining room. They expect that the extra tables will add between $2,000 and $5,000 to the restaurant's monthly revenue. The bank is willing to let the business have an intermediate-term loan of $50,000 for five years at an interest rate of 6.5 percent. Calculate the monthly payment and explain whether taking this loan is a smart business decision.
