In the $19^{\text{th}}$ century, Britain used a money system which included pence, farthings, shillings and pounds. The following conversions were used:

$\bullet$ $4\text{ farthings}=1\text{ pence},$

$\bullet$ $12\text{ pence}=1\text{ shilling},$

$\bullet$ $20\text{ shillings}=1\text{ pound}.$

How many total farthings were equivalent to $1$ pound and $5$ pence?
