Answer:
The answer is approx 75 months.
Step-by-step explanation:
We have P = 3000
r = 14%
Monthly payment = $60
We will use the formula :
![[(0.14/12) \times3000] / [1- (1+(0.14/12)^{-12n}]](https://tex.z-dn.net/?f=%5B%280.14%2F12%29%20%5Ctimes3000%5D%20%2F%20%5B1-%20%281%2B%280.14%2F12%29%5E%7B-12n%7D%5D)
Solving this we get n = approx 75 months. After 75 months few dollars will be left. And in the 76th month the balance will become negative.
For easy and better understanding, I have attached an excel sheet.
The answer is approx 75 months.
Answer: 34%
Step-by-step explanation:
Given
Price is marked down by 60% with an additional discount of 15% on the marked down price
Suppose x is the original price of the item
After marking down, it is

after additional discount it is

Effective discount on the item is

Thus, a person is paying
of the original price
Answer:
6F
Step-by-step explanation:
Let x be the temperature at noon
dropping means we subtract
The temperature at 9 pm was -4. That goes on the right hand side of the equals
x-10 = -4
Add 10 to each side
x-10+10 = -4+10
x = 6
The temperature at noon was 6 F
Answer:
2√42 ≈ 12.961
Step-by-step explanation:
All of the right triangles are similar, so ...
short leg/long leg = BC/AC = AC/CD
AC² = BC·CD = 7·24 = 168
AC = √168 = 2√42
Let s = the speed of the slower train in km/hrs+10 = the speed of the faster train in km/hrLet t = time in hrs for the slower train to go 160 kmt-5 = time in hrs for faster train to go 160 km---------------Slower train:(1)
160=s.t
Faster train:(2) 160=(s+10) .(t-.5)From (1)(1) t=160/s
use the relations given in following screenshot and then use quadratic equation.
