For this case we can make the following rule of three:

$ 400 -------------------> 40 hours

x ------------------------> 6 hours

From here, we clear the value of x.

We have then:

x = (\frac{6}{40}) * (400)\\x = 60

Therefore, Luz earns $ 60 for 6 hours of work.

Answer:

she earns $ 60 for 6 hours of work

To work out how much Luz earns, you simply have to follow 400/40=10, so she earns $10/hour. We can therefore establish that if she works for 6 hours, she'll earn $60.

To buy a car, you borrow $25,000 with a term of three years at an APR of 6.5%. What is your monthly
Finger [1]

Answer:

  $766.23

Step-by-step explanation:

The amortization formula is appropriate for this. (Better, use a financial calculator or spreadsheet.)

  A = P(r/12)/(1 -(1 +r/12)^-(12t))

where P is the amount borrowed (25,000), r is the annual rate (0.065), and t is the number of years (3).

Putting the given numbers into the formula, we have ...

  A = $25,000(0.065/12)/(1 -(1 +0.065/12)^(-36))

  A = $25,000(.00541667)/(1 -1.00541667^-36)

  A = $25,000(0.00541667)/(0.1767322)

  A = $766.23

The monthly payment is $766.23.

A graphing or scientific calculator is useful for these. Something like a TI-84, or any of the equivalents, will have financial calculations like this built in. There are also numerous apps available for phone or tablet that will do financial calculations.

Pls help me!!!! I'm stuck on how to solve this!!??
Luda [366]
Let A represent the value of the car after each year.
A= initial value (P)×(1+percent increase(r)) ^time
A=P×(1+r)^t
A=18710×(1+(-12%))^8
A=18710×(1-12%)^8
A=18710×(1-0.12)^8
A=18710×(0.88)^8
A= 6728.7619591115
The best approximation is 6729
Therefore the value of the car will be about $6729 after 8 years
Your answer is B.
