(a)
Toexplain: The recursive formula gives the final amount in Vitoria’s CD.
(a)
Explanation of Solution
Given:The recursive formula gives the amount
The recursive formula,
Where,
Interest of one-year CD with 5%
So, next year amount =
Victoria also decides to add $500 each year extra.
So,
Thus, the recursive formula represent the amount in Victoria’s CD account.
(b)
To compare: The amount of Victoria’s and Ursula
(b)
Explanation of Solution
Given: The recursive formula gives the amount
Recursive formula for Ursula,
First make table for some years amount of Vitoria and Ursula.
First year both are same amount.
In second year Victoria amount is more than Ursula. It increases continuously every year.
After 13 years Ursula amount is equal to Victoria amount in 6th year.
Hence , Ursula is growing but very slow as compare to Victoria.
