the cost of the furniture is 3210
she puts 12% down
3210 x (12/100)=385.20
lets find the balance
3210-385.20=2824.80
this balance needs to be paid back in 4 years
the monthly payment is 68.20
4 years x 12 months= 48 months
48 x 68.20=3273.60
her original balance was 2824.80
the finace charge is:
327.60-2824.80=448.80
we need to round to the nearest cent which is 448.80
