Sally needs to have some drywall and insulation work done in her house. she has received a quote from a professional drywall contractor to complete her repairs for $1,200. her neighbor steve says he can complete the same job for $800. sally could use a credit card to pay the contractor, but steve can only accept cash. sally’s credit card has a 14% apr for credit purchases and a 32% interest rate for cash advances. expecting to pay $50 of the principle plus appropriate interest each month, sally estimates that it would take her 24 months to pay off the contractor balance and 16 months to pay off the cash advance balance. in the end, would it be cheaper for sally to hire the contractor or her neighbor to complete the repairs?
