For interest yeilding credit card balance, the sooner the balance is paid off the lesser the interest that will be paid.
Therefore, given that <span>Darlene
has a balance of $3980 on a credit card with an APR of 22.8%. Paying
off her balance in 4 months will result in her
paying the least amount of interest</span>.
Constant rates are used to illustrate linear functions.
- The average rate of change is $9.0 per hour
- The function that models the table is:
- The amount earned in 7.5 hours is $67.5
<u>(a) The average rate of change</u>
This is calculated using:
So, we have:
Hence, the average rate of change is $9.0 per hour
<u>(b) A function that models the table of values</u>
Let x represent hours, and y represent the earnings.
So, we have:
Where:
m =Rate = 9.0
So, we have:
Expand
Represent as a function
Hence, the function that models the table is:
<u>(c) Amount earned for 7.5 hours</u>
This means that x = 7.5
So, we have:
Hence, the amount earned in 7.5 hours is $67.5

Hi hhhhhhhhhhhhhhrhrjfjfjfjfjgjgj
Given:
Consider the complete question is "A speed walker covered mi in hour. How far will he walk in 3/4 hours if he walks twice as fast?"
A speed walker covered mi in hour.
To find:
Distance covered by him if in 3/4 hour if he walks twice as fast.
Solution:
We have,
It means a speed walker covered mi in hour.
If the speed is twice then he can cover double distance is same time.
Distance covered by him if in 3/4 hour if he walks twice as fast is
Therefore, distance covered by him is 9 mi.
