Answer:
Borrow from credit card has lower EAR
Explanation:
solution
we will apply here EAR formula that is
EAR = [tex](1+\frac{r}{m} )^{m}-1[/tex]
here r is rate of interest
and m is compounding frequency
and 13% compounded monthly
so
EAR = [tex](1+\frac{0.13}{12} )^{12}-1[/tex]
EAR = 0.1380324816
EAR = 13.80324816 %
and
Borrow from parents at 7% payable every six months
so
EAR = [tex](1+0.07)^{2}-1[/tex]
EAR = 0.1449
EAR = 14.49 %
so
Borrow from credit card has lower EAR
