Cynthia has the choice of taking out a 25-year loan for $155,000 at 4.4% interest, compounded monthly, or the same loan at 20 ye
LUCKY_DIMON [66]

Answer: Less than $100,831

Step-by-step explanation:

There is an equation for the calculation monthly payment which is:

x = p × r × (1+r)^n / (1+r)^n - 1

where,

p= the amount of loan, which is $155,000.

r = monthly interest rate, which is (4.4/12)/100 = 0.00367

n = number of months for paying back, which is 20 × 12 = 240

Since we have all the values, we plug them in and solve.

x = 155,000 × 0.00367 × (1.00367^240) / (1.00367^240) - 1

x = $972.27

Therefore, the monthly payment is approximately $972.3. We csn now multiply it by the number of months in order to get total payment:

$973.3 × 240 = $233,352

Therefore, the total amount, which is the loan plus the interest, will be 233,352 dollars.

To find the amount of interest, we subtract the loan from total amount:

= $233,352 - $155,000

= $78,352

The dollar value v(t) of a certain car model that is t years old is given by the following exponential function.
dimaraw [331]

Answer:

v(0) = 32,000 . . . dollars

v(13) = 16,427 . . . dollars

Step-by-step explanation:

The initial value is the value of the function for t=0. Put that into the formula and evaluate.

v(0) = 32,000(0.95^0) = 32,000 . . . . dollars

__

The value after 13 years is the function value for t=13. Put that into the formula and evaluate.

v(13) = 32,000(0.95^13) ≈ 32,000·0.513342 ≈ 16,427 . . . . dollars

On Tuesday, Karen finished all her chores in 3/4 of an hour. On Wednesday, she finished her chores in 5/12 of an hour. How much
IRISSAK [1]
1 hour = 60 minutes

Tuesday: 60 divided by 4 = 15. Karen did it 3/4 of a hour so we multiply 15 by 4 which is 45. 45 equals 45 minutes. On Tuesday, Karen finished her chores in 45 minutes

Wednesday: first we divide 60 by 12 which is 5. 5 would equal 5 minutes. now we multiply 5 by 5 which is 25. Karen finished her chores in 25 minutes.

Answer: Karen finished her chores 20 minutes faster on Wednesday than Tuesday.

Hope this helps!
