Suppose that a car dealer offers to sell you a car for $16500 or for payments of $275 per month for six years. To figure out what monthly interest (x) you’re actually being charged, you’d have to solve the equation:f(x)=60x(1+x)^72-(1+x)^72+1=0

Answer 1

Plot this on your calculator:
y=60*x*(1+x)^72-(1+x)^72+1
then notice where the x intercept is..
