Answer:
The Cost of wallet was $26.30.
Step-by-step explanation:
Given:
Total billed after redeeming voucher = $34.45
Voucher worth = $5
We need to find the cost of Wallet.
Solution:
Let the amount paid for groceries be 'x'.
Now Given:
She purchases a wallet that amounted to double the price she paid for the groceries she bought.
Cost of wallet = 
Now to find the cost of wallet we will consider the amount before redeeming the voucher.
Hence Total bill before redeeming the voucher = 
Now We can say that;
Total bill is equal to sum of Cost of wallet and Cost of groceries.
framing in equation form we get;

Dividing both side by 3 we get;

Cost paid for groceries = $13.15
Cost paid for wallet = 
Hence the Cost of wallet was $26.30.
It does not say simple or compound interest.
Simple interest is rarely used these days, so assume compound.
Use the standard formula:
future value = present value*(1+rate/n)^(nt)
n=number of times interest is compounded per year (=1)
t=number of years
Plugging values,
200=100(1.09)^t
1.09^t = 2
take log
t(log(1.09))=log 2
t=log(2)/log(1.09)=0.6931/0.08618=8.04 years.
