Answer:
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount taken as loan
R represents interest rate
T represents the duration of the loan in years.
1) From the information given,
P = cost of gym = $2200
R = 6%
T = 3 years
I = (2200 × 6 × 3)/100 = $395
The total amount that he would pay after 3 years is
2200 + 395 = $2596
If he decides to continue going to the gym, the total amount that the would pay in 3 years(3 × 12 = 36 is
80 × 36 = 2880
Therefore, paying for the gym would cost more. He should take the loan.
2) if she takes the loan, the interest would be
I = (18000 × 7.5 × 5)/100 = $6750
The total amount that she would pay back after 5 years is
6750 + 18000 = $24750
Since the value that would be added to her house is $25000, therefore, she should buy it.
The cost of 10 apples would be 26 dollars because each pound is 14.
Answer:
<h2>-
56,667cents</h2><h2>
- 6.17%</h2>
Step-by-step explanation:
Before we can determine the monthly loan paymnet, we must first calculate the total amount paid at the end of 6years.
Amount = Principal + Interest
Given Principal = $30,000
Interest = Principal * rate * time/100
Interest = $30,000*6*6/100
Interest = $10,800
Amount = $30,000+ $10,800
Amount = $40,800
If amount paid after 6years is $40,800, my monthly loan payment = $40,800/72 ≈ $566.67 to nearest dollar.
since $1 - 100cents
$566.67 = 100 * 566.67
$567 = 56,667cents
Monthly loan payment to nearest cent will be 56,667cents
EFF = (1 + r /n)^n - 1
r is the rate and n is the number of period per year which is 12months
%EFF = EAR = (1 + 0.06 /12)^ 12 - 1
%EFF = 1.005^12
%EFF = 1.061678 - 1
%EFF = 0.061678
%EFF = 6.17% to 2dp
Adding the numbers gives us a total of 65
Jan = 20/65 = 30.7% = 31%
Feb = 25/65 = 38.4% = 38%
Mar = 1/65 = 1.5% = 2%
Apr = 3/65 = 4.6% = 5%
May = 16/65 = 24.6% = 25%
I believe ur answer is 30%
Answer: a) √50
b) n = 1 + 7i
Step-by-step explanation:
first, the modulus of a complex number z = a + bi is
IzI = √(a^2 + b^2)
The fact that n is complex does not mean that n doesn't has a real part, so we must write our numbers as:
m = 2 + 6i
n = a + bi
Im + nI = 3√10
Im + n I = √(a^2 + b^2 + 2^2 + 6^2)= 3√10
= √(a^2 + b^2 + 40) = 3√10
a^2 + b^2 + 40 = 3^2*10 = 9*10 = 90
a^2 + b^2 = 90 - 40 = 50
√(a^2 + b^2 ) = InI = √50
The modulus of n must be equal to the square root of 50.
now we can find any values a and b such a^2 + b^2 = 50.
for example, a = 1 and b = 7
1^2 + 7^2 = 1 + 49 = 50
Then a possible value for n is:
n = 1 + 7i
