Maraming salamat po, same rin po ba ang gagawin kung ganito naman ang tanong..

padouble check sa answer sheet

#7 same steps pero annually naman given, monthly yung unknown

F1(annually) = F2(monthly)

(1 + 0.20) = (1 + [r ^(12)/12] )^12 (multiply both sides with 1/12)

(1.20)^(1/12) = 1 + [(r^12)/12]

(1.20)^(1/12) - 1 = (r^12)/12

[(1.20)^(1/12) - 1 ] 12 = r^12

answer x 100 = r^12

#8 same process semi annual=2
