Answer:
Step-by-step explanation:
This is the case of an exponential growth. The function for exponential growth is,
where,
- y(t) = value after time t = f(x)
- y₀ = initial value = $120,000
- r = rate of growth = 5.5% = 0.055
- t = number of periods = x years
Putting the values,
Simple interest rate is given by:
I=(PRT)/100
let the amount invested in 5% S.I. be $x and amount invested in 6% S.I. be $(8000-x)
Interest obtained from 5% will be:
I=5/100×1×x=0.05x
Interest obtained from 6% will be:
I=6/100×1×(8000-x)=0.06(8000-x)
therefore total interest earned from the to schemes will be:
0.05x+0.06(8000-x)=438
solving for x we obtain:
0.05x+480-0.06x=438
0.05x-0.06x=438-480
-0.01x=-42
x=-42/(-0.01)
x=$4200
hence amount invested in 5% S.I. is $4200 and amount invested in 6% S.I. is (8000-4200)=$3800
Answer:
-58
Step-by-step explanation:
-24 - 26 = -50
-50 - 8 = -58
Answer:
Katelyn's monthly payment for the loan is $ 2,032.52
Step-by-step explanation:
The formula given is explicit,we can solve for monthly payment using the below formula
P=L(1-r/r-r^n+1)
r=1/(1+i)
i=5.6%/12=0.47%
5.6% is an annual interest rate,it would be appropriate to restate in monthly terms
r=1/(1+0.47%)=0.995
n=5 years*12 months=60
L is the loan amount of $100,000
P=100000*(1-0.995)/(0.995-0.995^60+1)
=100000*(1-0.995)/(0.995-0.74)
=100000*0.005/0.246
=$ 2,032.52
