Question

On a website that sells funny T-shirts, the number of customers has been falling 10% per month. If the site had 14,000 customers this month, then how many should it expect to have 10 months from now?

Answer 1

4881 customers

Explanation:

Given :

⇒ Falling 10% per month

⇒ 14,000 customers this month

============================================================

Creating the function :

⇒ Let y = remaining customers and x = number of months from now

⇒ y = (14,000)(1 - 0.1)ˣ = (14,000)(0.9)ˣ

==========================================================

Solving :

⇒ y = (14,000)(0.9)¹⁰

⇒ y = (14,000)(0.34867844)

⇒ y = 4881 customers (nearest whole person)

Answer 2

Rate of fall is 10%=0.1

• Tim e=10months

Now

• y=ab^x
• y=14000(1-r)^t
• y=14000(1-0.1)¹⁰
• y=14000(0.9)¹⁰
• y=4881 customers
