The total amount of cash money that Korey have is the summation of his savings and his inheritance which is equal to Korey cash = $8500 + $25,000.
To identify the amount needed to be funded by loans or investors, we need to know first the total of expenses plus set-up plus operation expenses and other expenses to operate the bookstore subtracted by his savings.
Thus, let "AL" be the amount needed through loans while letting "TE" for total expenses.
AL=TE-($8500+$25000)
AL=TE-$33,500
This is the equation needed to determine the amount needed.
