Question

Gente, me ajudem nesta questão 25. por favor! por favor!

Answer 1

25
a
C = 1.400
t = a ano = 12 m
i = 0.9% a m  = 0.9/100 = 0.009
M = 1400 ( 1 + 0.009)¹²
M = 1400 ( 1,009)¹²
M = 1.400 * 1,113510 
M = 1.558.91 ****

b

i = 0,7% a m =  0.7/100 = 0.007
3.304,60 = 2.500 ( 1 + 0.007 )ⁿ
3.304.60 = 2.500 ( 1,007)ⁿ
1.007ⁿ = 3.304.60/2.500
( 1,007)ⁿ =1,32184
n * log 1,007  = log 1,32184
n * 0.0030294 = 0,1211788
n = 0.1211788/0.0030294
n = 40 m
