Asubscription-based website sends out email reminders to 15,000 customers whose subscriptions are due to be renewed, inviting them to renew at a discount. after the email is sent, the number of customers whose subscriptions are due to be renewed decreases at a rate that compounds hourly, for a per-day decrease of 14.4%. the number of such customers after n days is given by the expression below. what does (1-0.144/24) represent? a. the decay rate, which reveals the hourly rate of change in the number of customers whose subscriptions are due to be renewed b. the initial number of customers whose subscriptions are due to be renewed c. the number of customers whose subscriptions are still due to be renewed after one day d. the change per hour in the number of customers whose subscriptions are due to be renewed

Given that a subscription-based website sends out email reminders to 15,000 customers whose subscriptions are due to be renewed, inviting them to renew at a discount. After the email is sent, the number of customers whose subscriptions are due to be renewed decreases at a rate that compounds hourly, for a per-day decrease of 14.4%.

So the above situation can be modeled by decay formula

Where P=initial value = 15000

r= per day decrease rate = 14.4%=0.144

n=number of hours = 24

t= number of days

A= present value.

So we get equation:

Now compare that with given expression:

given expression represents only the parenthesis part which is basically called growth/decay factor.

which best matches with choice A.

Hence final answer is:

A.

the decay rate, which reveals the hourly rate of change in the number of customers whose subscriptions are due to be renewed

explanation:

the loan estimate encourages consumers to shop. since it is the lenders who are required to issue a standardized loan estimate in a specific time frame, this way consumers are provided an opportunity to compare lenders and their products. otherwise consumer wouldn't know the benefits offered by other lenders.  

if a loan originator does not provide a loan estimate within 3 business days of receiving a completed loan application, that lender is in violation. lenders are required to issue a loan estimate within 3 days of applying for a loan or within 7 days prior to closing. having a loan estimate has following information.

not having loan estimate won't give you an idea of money to be borrowed.

you get to know your interest rates.

you also get to know if your interest rate can or may vary.

not having a good faith estimate can keep you unaware of aforementioned points.

the translated point is (5,2)
