answer C
Step-by-step explanation:
Answer:
$25,626.53
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 8.5% into a decimal:
8.5% ->
-> 0.085
Now lets plug in the values into the equation:


Lastly, subtract the total from the initial balance:

Michelle earned $25,626.53 in interest.
The boundary line should be solid because it have a 'great/less than or equal to' sign
Answer:
approximately 7 hours
see the explanation
Step-by-step explanation:
The picture of the question in the attached figure
Let
x ----> the time worked in hours
y ----> the amount earning in dollars
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>
so
In this problem we have a proportional relationship
step 1
Find approximately how many hours would it take Delia to earn $250 ?
Looking at the graph
For y=$250 The value of x is approximately 7 hours
see the attached figure N 2
step 2
Find the exact value
from the graph take the point (5,175)
Find the value of k
----> 
The linear equation is

For y=$250
substitute

solve for x
