An exterior angle is equal to the sum of the two opposite inside angles.
T + 31 = t + t-29
Simplify:
 T + 31 = 2t -29
Add 29 to both sides:
T + 60 = 2t
Subtract 1t from both sides:
T = 60
 
        
             
        
        
        
Susan's monthly payment will be $117.93.
We have Susan take out a personal loan for $3,500 at an interest rate of 13% compounded monthly.
P=3500
r=30%
t=3
<h3>What is the amortization formula?</h3>
 
Where A is the payment,
P= principal, 
r =the annual interest rate 
t is the number of years.
use the given value in the formula we get

A=117.9288 
A= 117.93
Susan's monthly payment will be $117.93.

Answer:
The costs of the plan are $0.15 per minute and a monthly fee of $39
Step-by-step explanation:
Let
x ----> the number of minutes used
y ----> is the total cost
step 1
Find the slope of the linear equation
The formula to calculate the slope between two points is equal to

we have the ordered pairs
(100,54) and (660, 138)
substitute


step 2
Find the equation of the line in point slope form

we have

substitute

step 3
Convert to slope intercept form
Isolate the variable y

therefore
The costs of the plan are $0.15 per minute and a monthly fee of $39
