Answer: To find the finance charge you multiply the balance times 0.23 / 12 .
To find the interest charge to an account, you have to multiply the balance by the percent rate (APR).
The problem in this case is that interest is charged monthly, but the rate is yearly.
To fix this problem, just divide the rate by 12.
0.23 / 12
Answer:
-13t - 5z
Step-by-step explanation:
-6t + 2z - 7z - 7t
= -13t - 5z

Hello!</h2>
The answer is:
The distance to over by Adam to get to the park is 108 miles.
<h2>
Why?</h2>
To solve the problem, we need to write two equations using he given information about the times and his speed.
So,
For the first equation we have: Travel to Disney Park


For the second equation we have: Travel back from Disnery Park



Then, if Adam covered the same distance going and coming back, we have:





We have that the speed when he was going to Disney Park was 27 mph.
Now, to calculate the distance, we need to substitute the obtained speed in any of the two first equations.
Therefore, substituting the speed into the second equation, we have:


Hence, we have that the distance that Adam should cover to get to the park is 108 miles.
Havea nice day!
Answer:

Step-by-step explanation:
Let the x-axis be the time (in years) and the y-axis the value of the fax machine (in dollars).
We know that the initial value of the fax machine is $100; in other words, when the time is zero years, the value is $100, or as an ordered pair (0, 100). We also know that after 1 year the value decreases to $80, so (1, 80).
Now we can find the slope of the line passing through those two points using the slope formula

where
is the slope
are the coordinates of the first point
are the coordinates of the second point
Replacing values:


Now, to complete our model we are using the point slope formula

where
is the slope
are the coordinates of the first point
Replacing values:




We can conclude that the correct linear depreciation model is 
Since you are given that the student registered early, the total number you deal with is all students who registered early.
211 + 329 = 540
number of undergraduates who registered early = 211
Among students who registered early:
p(undergraduate) = 211/540
