Answer:
The principal must be = $8991.88
Step-by-step explanation:
Formula for compound interest is:

Where A is the amount after 't' years.
P is the principal amount
n is the number of times interest is compounded each year.
r is the rate of interest.
Here, we are given that:
Amount, A = $15000
Rate of interest = 13 % compounded quarterly i.e. 4 times every year
Number of times, interest is compounded each year, n = 4
Time, t = 4 years.
To find, Principal P = ?
Putting all the given values in the formula to find P.

So, <em>the principal must be = $8991.88</em>
Answer:
4.847
Step-by-step explanation:
divide 8.24 by 1.7
8.24 /1.7 = 4.847
Set up the equation ... 60 + 40X = total charges... where X is the number of hours (8.5)
60 + 40(8.5) = ?
60 + 340 = ?
400 = total charges

Answer:
x= 7
Step-by-step explanation:
Theorem: The sum of the angles of a triangle is 180
Memorize that theorem
8x - 9 + 63 + 70 = 180
8x + 124 = 180
8x = 56
x= 7
