Problem #$4$: Shopping Spree

Isabel is going shopping using her debit card and has a tendency to overspend. Complete the function, balance$\_$remaining, which takes two arguments: initial, the integer amount of money Isabel starts with in her account; and transactions, the list of purchases Isabel is charging to her card.

Each transaction in the transactions list is a string of the following format:$$

'Store Name $-$ $price'$$

The price is always an integer.

If Isabel can afford all of her transactions, your function should return the string

'Balance Remaining: $balance'$$

where balance is her remaining balance. If Isabel attempts to overspend, cancel the transaction $($i$.$e$.,$ don$$t subtract the transaction amount from her current balance$),$ and return the string

'Declined at Store Name: $balance'$$

where Store Name is the name of the store where her charge was declined, and balance is the amount of money she has remaining.
