Explicación paso a paso:
12.
Monto = 5208
Capital = C
Tasa de interés = 2% trimestral
Tiempo = 2años = 8 trimestres
M = C + Cr%t
5208 = C + C(2%)(8)
5208 = C + 16%C
5208 = 116%C
C = 4489,65
13.
C1 + C2 = 27000
I1 = I2
C1r%1t = C2r%t
C14% = C25%
4C1 = 5C2
C1 = 5k
C2 = 4k
C1 + C2 = 27000
9k = 27000
k = 3000
Capital menor C2 = 4k, C2 = 4(3000) = 12000
14.
C1 + C2 = 28000
C1(30%)/C2(50%)4 = 5/4
3C1/2C2 = 25/2
3C1 = 25C2
C1 = 25k
C2 = 3k
C1 + C2 = 28k = 28000, k = 1000
Capital menor = 3k = 3(1000) = 3000
15.
I = C(63%)(t)
125%I = C(63%)(t+2)
125%(C(63%)t) = C(63%)(t+2)
(5/4)t = t + 2
5t = 4t + 8
t = 8años
16.
Tres aumentos de 10%
110%110%110% = 121(110)/100% = 133,1%
133,1% - 100% = 33,1%
El aumento final será de 33,1%
17.
Capital = 4000
Tiempo = 4 meses
Tasa de interés = 0,4%bimestral = 0,8% mensual
Interés = I
Monto = M
I = 4000(0,8%)(4)
I = 128
M = C + I
M = 4000 + 128 = 4128
18.
C1 = x
C2 = 20000 + x
9000 = x(6%)t1
150000 = xt1
10000 = (20000+x)(4%)t2
10000 = 800 + 4%xt2
9200 = 4%xt2
230000 = xt2
t1 = 15k
t2 = 23k
19.
288 = 1800(8%)t
288 = 144t
t = 2años = 720 días
20.
90 días = 3 meses
60 = 1800(r%)3
60 = 54r
r = 1,1% mensual
